wd 2tb external drive - unknown, not initialized and unallocated

Question: wd 2tb external drive - unknown, not initialized and unallocated

It is my brother's hard drive & it has very important data related to his working. It is a 2tb WD my passport ultra external hard disk which was used as NTFS with only one partition.
My brother told me that he deleted some data from the drive by mistake and was recovering the data from the drive but all the windows recovery programs he used just hanged after few minutes (which is also a sign of bad sectors). Then he done the blundered mistake by formatting the drive, the formatting also not completed due to hang situation.

Now the current situation is that the drive is not showing in the windows explorer and when I open the disk management ,the popup came up for initializing the disk either as MBR or GPT. When I try to initialize the disk, it gives me this error:- "The request failed due to a fatal device hardware error". I have attached a few screenshots below.

I have tried cloning the drive with clonezilla, tried booting the drive with parted magic, Hire n boot and system rescue CD but neither of them recognized the drive and some also rejected to boot with the drive attached.
Now currently i am scanning this disc for recovering the lost partition in the 'Partition Recovery Wizard' software according to the advice on some old thread here, but this software has detected my disk as 'bad Disk' in the file System column as you can see in the fifth image, so i don't have much hope with this software.

Please tell me if there is any hope left for drive like trying any other partition recovery software or cloning the drive via some tools.

Thanks in advance

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: wd 2tb external drive - unknown, not initialized and unallocated

Hello nsingla and I am sorry you and your brother have this problem!

Things don't look so good now. You've done and tried a lot with aim you need, still looks like the drive's partition table and/or file system are corrupted to a stage that prevents other software to work correctly onto the drive.

I could additionally suggest trying to scan and repair the drive. Try downloading the WD ultra Drive Utilities for Windows and see if you could repair the drive:

Support Answers

If nothing works, the drive is probably too damaged and beyond repair. Hope this is not the case. But perhaps the worst part for the drive was the formatting attempt. Which, by definition, would delete everything from the HDD.

Good luck and post back with results!

Answer:How do i fix unknown, not initialized and unallocated external hd?

Sorry to be the bearer of bad news ... but I had almost exactly the same thing happen to me on a Seagate 2TB hard drive. Working for months, even passing surface checks with no errors and then, one day -- "bad disk".

I've tried every data recovery app I could find against it (4 of them) and none of them find anything.

I've had drives fail me over the years and have never run into this situation where the drive powers up but NOTHING can be recovered from it.

So, I've resorted to sending it off to a local data recovery outfit

Answer:How do i fix unknown, not initialized and unallocated external hd?

Right click on it and choose Create Parittion. Choose the type of partition. Then format it. I recommend doing the slow format. It may take an hour or so, but I think you're better off in the long run.

Hello
I got my 1tB WD external disk and it's not working as it used to. The problem came from nowhere, suddenly, totally unexpected. There is/was my precious data on it which I collected for 10+ years and I'd like not to lose it.

Origin:
It was working fine a day ago, no problems occured. Hasn't been unplugged since then. Has never fallen. Has never had any kind of error. But: I've seen some kind of ".COM not responding" problem on my PC (don't remember, closed it immediately). I believe my laptop is in a good and healthy condition.

So, what my WD HDD does is:
- it can be seen as a device by my computer. I can plug it out safely.
- diode shows that it's working (not showing the data transfer activity)
- nothing else

What I see in Device Management/Storage is (as in the title):
Screenshot by Lightshot

What programs I used to try to restore partition:
- Mini tool Partition Recovery Home Edition (quick and deep scan, no results. Shows disk as a Bad Disk)
http://prntscr.com/2wpy8s
- Mini tool Power Data Recovery (pro, non-free tool, however after scan there was no results)
- Find and Mount (no results)
- TestDisk (quick and deep scan, no results)

What I haven't tried doing is connecting the HDD directly to the laptop.

Any suggestions?

Answer:External HDD shows as Unknown, Not initialized, Unallocated. Restore?

You should try directly conmcting it. If that does not work, try this: Recover a flash drive turned RAW ? Partition Wizard and TestDisk. Do recovery with partition wizard. (Don't mind the name) But if that does not work, your drive is dead. Like a wise man said, backup, backup, backup!

Answer:Disk 1 is unknown, not initialized, unallocated, Please help

Start with this free tool. You should try to recover the partition before worrying about recovering the data. If you can recover the partition, the files should be OK if they haven't been over-written.

Best Free Partition Manager Freeware and free partition magic for Windows 7, Windows 8, Windows Vista and Windows XP 32 bit & 64 bit. MiniTool Free Partition Manager Software Home Edition.

Select Partition Recovery Wizard. Choose the drive, then full disk, quick scan. Quick Scan may take 5 or more hours.

If the partition is eventually found, select and double click on it. You should then see all files in the Explorer.

i tried to plug it in another computers but nothing changed.
i have many thing in that drive i need them so could you please help me ?
 

Answer:my external hard drive is unknown and not initialized

I assume you have tried another usb cable; that is the very first thing to do.
If you have already done the above, then the next thing I would do would be to pull the drive out of the enclosure and connect it as an internal drive. Note you must have a working desktop to accomplish this task. If that does not work, you can send the drive to a data recovery shop. This last step is NOT cheap so get an estimate. A simple recovery using software can run $250 or so plus the cost of whatever media you want the data copied to AND it goes way up from there.
i have many thing in that drive i need them so could you please help me ?Click to expand...

Data you do not backup is data you do not care about AND you should expect to lose said data. All drives fail; it is only a question of when your drive will fail.

Hello,

I have used the tittle from another thread as my issue is very similar, only none of what is posted there worked for me.

So I have a WD 500gb HDD. (Actually I am not 100% sure it is a HDD and not a SDD)
I have plugged it in various PC and laptops. When doing so, you get the usual sound que. It also installs the driver according to the little pop up window.
However after that, the drive is not visible in "My Computer".

When I check the drive in Computer Management>Disk Management, it wants me to initialise the disk. Which, I know I do not want to do (thanks to one of your earlier posts) as this will over write my data.
In Disk Management the disk is "Unknown" and "Not Initialised" It also does not give any volume. Pics of both of these attached.

I have tried using Partition Wisord free. It does not even see the drive.
I have tried using Photorec. It does not see the drive.
I have used R-Studio. It does see the disk, but I am not able to scan it. Again also no disk volume. Again Picture attached.

I am hopeful for a solution, as I feel like the symptoms suggest that I do not have a head misalignment. But I might be wrong on that.

Hoping for someone with some mad skills to help me out here.

Thanks in advance!

I had a WD 2TB external drive which I transferred successfully to a USB 3.0 enclosure months ago. Then I moved and the drive has been packed away in the trunk of my car since.

I just got it out as I need some files on it, and when I hooked it up it didn't work: the computer recognized it as a CD drive or something... in Computer it would not show up or show up as just a drive letter ... in disk management it said No Media. I tried it on another PC too to no avail.

After much research, the most likely solution looked to be to get a new enclosure. So I did, but the drive still isn't working, but in a different way.

When I first hooked it up, all looked well: the system tray showed correct recognition of the drive and enclosure type/brand and installed the drivers successfully.

But the drive no longer shows up in Computer at all, and in disk management it now prompts me to initialize the disk, and has it marked as Unknown, Not Initialized.

I have spent all day trying to fix this problem, and have read a million threads on different sites and tried everything, to no consequence. I need the files on the drive, and have tried all of the following:

Do NOT initialize it. With a usb stick or dvd Puppy Linux boot firmly in place ready to boot, can you reconnect the WD 2TB drive back to the computer like it was in the old days? Boot Puppy Linux, copy all the data folders and files onto another reliable external media. If that does not work, you might be heading for a local business-oriented computer fix-it place. However, let's see what others here might want to add.

Hi, i'm new on this forum. I was searching for an answer to this issue in a lot of threads but i didn't find something to fix it.

I built an external hd using the hard disk of my old laptop (Fujitsu MHV2120AH PL) and a Woxter i-Case 240.

When i connected it via USB i went to the Disk Manager and saw the unit as "Disk 1 Unknown Not Initialized". But there was something else, the disk has a size of 120GB but the Disk Manager shows only 700MB.

The Disk Manager didn't allowed me to format this partition and when I press on "Initialize disk" it didn't do anything.

I used a Linux Live CD and I had the same issue, i tried to create a new partition table but it didn't create it and GParted didn't allow me to create a new partition answering that i need a partition table first.

I tried with Diskpart without any result too.

This HD had an Windows XP installed on the old laptop and before dissamble it i made a quick format with the Bootable CD of my laptop. The quick format was interrupted when the program was copying the files necesary to install Windows XP.

Do you have any idea?

Answer:Unknown - Not Initialized Disk (External HD)

Hello Matterito!

You could try a couple of things: changing the enclosure, as this one's controller may be corrupt, or hooking up the disk directly to the computer.
Also, see if your USB drivers need updating.

Following this, it may be that your disk is just damaged. It could be just that the partition table is corrupted, so may be writing full zeros to the disk and repartitioning and reformatting it would help fix the issue. That is in the case that you don't need the information on the drive.

Hi,

I've been recovering data from three older internal hard drives for a friend, by way of an external HDD enclosure connected via USB to my laptop. It went well for the first two HDDs but the third, well ....

It's a Maxtor DiamondMax 10 HDD, 120 GB and is also marked SATA150.

(1) On most occasions, the HDD in question does not appear under My Computer. Under Devices and Printers, I see the external HDD enclosure as "USB to ATA/ATAPI bridge" (but not the HDD). In Disk Management, I see my internal drives and CD/DVD ROM but for the HDD in question, only "Disk 2, Unknown, Not Initialised" - I get the option to initialise it as MBR or GPT (I cancel at that point).

(2) On rare and seemingly random occasions, my laptop does pick up the HDD as drive F: but usually asks me if I want to format it (nope!). At this point it also appears under Devices and Printers, My Computer and in Disk Management as 'RAW' and 'healthy'.

(3) On three occasions, I have seen the drive name; on two occasions, all of the files - and on one occasion, I was able to copy four files across to my laptop (before losing visibility of it). So I know all the files are there.

However the HDD disconnects itself (or is disconnected) quite quickly, such that I am back to position (1) for the vast majority of the time.

I have tried TestDisk and EaseUS Data Recovery Wizard, which do not see the HDD. I have also tried MiniTool Partition Wizard, which mostly does not see the HDD but on one occa... Read more

Hi empog,

Welcome to Seven forums.

It could be an either an issue with the harddrive itself or it is formatted in a partition which is not recognized by windows.

Once the harddrive is connected open command prompt and type diskpart and hit enter. Then type list disk and hit enter.

Whatever information is displayed kindly post a screenshot for the same.

Later, I connected it to several computer and it would install and be detected in Device manager, Disk Management and even devices and printers but it does not show in My Computer nor does autoplay options pop up.

Answer:Disk1 Unknown Not Initialized error for external HDD

My Passport is Western Digital. Isn't it?

I am not placing much hopes on your drive. It doesn't even show the capacity.

Anyway let us check your drive with Datalifeguard Diagnostics for DOS.

Please see this post and execute. Please help,disk 1 unknown not initialized (western digital external)

1. Disk management showing disk 1 -unknown- -not initialized-

2. When i tried to initialized it show -incorrect function-

3. I tried the recovery software but all of them cant detect my external HDD

4. The Data Lifeguard Diagnostic from western digital managed to detect my external and showing there is bad sector but when i tried to repair, it give me this message -unable to repair bad sector-

Please help!!! is there any chance i can fix this?

Answer:Please help,disk 1 unknown not initialized (western digital external)

I guess there is mechanical problem with the hard drive. you can try checking and repairing bad sectors (http://www.articlesbase.com/hardware...s-6907958.html), or just send it to some drive repair center.
but, if there is important files on the drive, you'll have to recover data before repairing it.

Yesterday, I was working with my PC while my 1TB Seagate external hard (Amazon.com: Seagate FreeAgent GoFlex 1 TB USB 3.0 Ultra-Portable External Hard Drive in Black STAA1000101: Electronics) was plugged in via USB. The USB connection was a little bit loose.

Then when I was plugging a USB flash memory in, I noticed that the external hard was disconnected.
I connected it again, but it didn't appear in My Computer.
Here is the state in Disk Management and Device Manager:



After that, I plugged out the "SATA to USB converter" from the hard and connected it directly to SATA cable inside the PC case (like internal HDD), but this time nothing showed up in Disk Management, Device Manager and BIOS. However, it took a long time for the system to boot.


I searched and read lots of threads and tested some other stuff:

Hi there Sedhadi,

If your HDD is failing the manufacturer's tests it is probably dead. IF you need to get your data back look for a reputable data recovery company in the area.
Hope that helps.

I had a WD 2TB external drive which I transferred successfully to a USB 3.0 enclosure months ago. Then I moved and the drive has been packed away in the trunk of my car since.

I just got it out as I need some files on it, and when I hooked it up it didn't work: the computer recognized it as a CD drive or something... in Computer it would not show up or show up as just a drive letter ... in disk management it said No Media. I tried it on another PC too to no avail.

After much research, the most likely solution looked to be to get a new enclosure. So I did, but the drive still isn't working, but in a different way.

When I first hooked it up, all looked well: the system tray showed correct recognition of the drive and enclosure type/brand and installed the drivers successfully.

But the drive no longer shows up in Computer at all, and in disk management it now prompts me to initialize the disk, and has it marked as Unknown, Not Initialized.

I have spent all day trying to fix this problem, and have read a million threads on different sites and tried everything, to no consequence. I need the files on the drive, and have tried all of the following:

I ran BIOS diagnostics on a Dell OptiPlex 3010 yesterday and received an error code (2000-0142) - short self test unsuccessful. I pulled the drive and swapped a new SATA drive to get the user back up and running quickly. I'm trying to connect the drive with the error to my laptop using a StarTech USB 2.0 to IDE SATA Adapter. When I open Disk Management I see Disk 0 (my laptop drive) and Disk 1 (the connected drive). It says Unknown / Not Initialized. When I right click and try to initialize it says "The device is not ready." I've tried the more actions > refresh / rescan.

Hi guys. I'm new here. I've tried to read all the discussion about how to fix the unallocated hard drive but I just can't understand it as the cases were pretty much different than I'm facing of.

Here's my problem.
Yesterday my external hard drive seems normal, everything is fine, until there's a blackout and I have to put "sleep" to my laptop. After the power got back, the hard drive suddenly gone and when I check the list of drives under "Disk Management", it showed up as "Disk 1 - Unallocated".

(I've attached screenshots here for your viewing)

My external hard drive is WD My Passport 1TB. It contains a lot of valuable data I cannot afford to lose. I really hope there's a way to fix this, and once I get back all of those precious data I will buy another HD to transfer them ASAP because I cant let this happen to me again.

Your help is so, very much appreciated.
Any questions regarding my problem, let me know. I'll provide all of the details you guys need.

NOTE
1) I've tried TestDisk but on the "Analyse" process, it says "read error"
2) I've changed cable, but the situation remains the same.
3) I've tried Recuva, but it doesnt recognize my external drive.

Hi!

First don't mess up with the WD drive settings.. download partition wizard 7 (its free)..then .. open it ..click wizard(menu) .. select partition recovery wizard.. and it will find the partitions on it i think.. that way you can recover your partition that has been lost.

Hay guys,
I have a WD external with a password property. When i plug it in my laptop it works fine but after i type the password the laptop freezes for a moment then the external gets disconnected and the process starts all over again and sometimes the autoplay message shows up (after i unlock the external) and when i try to open it the laptop also freezes and a message shows up saying: "parameters are incorrect". When i opened disk management (after reading posts from many websites) i found that the external is UNALLOCATED and NOT INITIALIZED.
Can any one pleeeeeeeease help me?

Answer:unallocated - not initialized

Not enough info.

Have you been using the external successfully before? As well as successful password entry?
Did you just receive it and now want to try to use it?
Do you want to maintain the password security?
Do you have data on it that would kill you to lose?
Have you been disconnecting it while its been mounted in the operating system? (That is not good)

If just received, & no data worries, why not try to initialize it in Disk Mgmt and give it a letter?

Greetings, I will cut right down to the issue at hand seeing that I've spent two hours on this so far and no luck. The drive worked perfectly yesterday. It might of been connected through the USB port when I had an error screen (blue screen) about my SD port and then the system restarted itself. I guess the external HD failure could come from this. At the same time, even the active torrents I had, on my internal HD with no link to my external one, got deleted from Utorrent.

I have followed Jumanji steps from another thread regarding the MiniTool Partition Wizard as well as TestDisk. TestDisk does not list Mybook in the drives list nor does chkdsk command. Here are the screenshots. Any help would be appreciated. Thank you!

Answer:WD My Book Not initialized / Unallocated

Hello DeadlyKnight and I am sorry to hear about the My Book! :/

Unfortunately, if the drive was connected to the system in the moment of the BSOD happening, it really could be a good enough reason for the drive's state now. The Cyclic redundancy check normally occurs because of damaged or faulty drives.

Additionally, the MiniTool software shows the drive as “Bad disk”. So retrieving the data may be hard for home environment. You could try booting a Linux-based Live CD and checking if the drive is there and accessible.

Otherwise, you may have to turn to professional data recovery help, if you need the data from the drive. :/ WD has partners in the field:

Last thing you could try on your own is to try and fix the CRC error, but it could also be not possible. This tutorial may help you:

Answer:external drive say it was online, not initialized, and sometimes RAW

Hi andremarb,

Welcome to SevenForums.

From the description of your problem, I would think that the cable could have got damaged due the unceremonious kick that the HDD received. So as a first step use a new cable and check how your external drive behaves.

If the problem persists, please start a new thread explaining your problem in detail. Furnish full details of your external drive make/manufacturer/ Model /Capacity along with a full screenshot of how the drive appears in Windows Disk Management. Please adhere to the guidelines here Disk Management - Post a Screen Capture Image

In the new thread, even if it is not me - so unreliable these days , some one else can address your concern. So move on with the new thread.

EDIT: Just noted that your post has been moved on to a new thread. But this post still holds - more details and screenshot after changing to a new cable.

Hi, thanks for trying to help me with this.

I recently moved and had my external hard drive disconnected and in storage for several months. It is a Western Digital model# WD500H1U-00. It has a separate power supply. There is a blue light on the front that is illuminated all the time, except when I connect the HD, then it will flash. When I got unpacked I hooked it up to my desk top and the computer would not access it. I then tried to install it on my laptop with no success. Since then I purchased a USB cord, with no luck.

This hard drive has a LOT of irreplaceable information on it. Formatting it is not an option.

Kevin at SpywareHammer.com was helping me with some other stuff and suggested I:

Regarding the ext HD, try this please:

1) Control panel===>administrative tools===>computer management===>Disk management

2) You'll Should see a list of Disks, Is Disk 1 listed with no partition letter assigned? if so continue

3) Right mouse click into the disk field, select Change drive letter and paths ===> choose a letter from the drop down, select OK. the HD should now be available.

No luck here either. When I right click on the disk field nothing happens. When I right click on the title block(?) I get: Initialize Disk (faded), Offline, Properties and, Help.

Hi all,

I'm having an issue where my external hard drive (WD Passport Ultra 2TB) is not displaying in my computer and is not initialized in Disk Management. This occurred after my computer crashed while I was pulling out data from the external hard drive. Now when I plug in the external hard drive, it has a clicking sound for a few seconds then stops with a blinking light.

I have tried using the MiniTool Partition Wizard and it does not detect it. When I open up Disk Management, it says that I need to initialize the disk before I can access it. I read somewhere that I will lose my files if I initialize this, so I have not done so. The Disk Management also does not show any unallocated space in it. Please see attached image.

Currently I just want to take out all the data from this hard drive before I let this drive go if I can't save it. Is there any hope for me to save my files?

Best regards,

Hi,

My problem is as follows:
External Hard Drive (1Tb WD Elements) that I've been using for a few months now has data on that I would very much like to keep.
It was working fine until yesterday in which I tried opening a VS project which became unresponsive, tried closing everything down and turning off computer which just froze the computer leading to a hard reset (button held for 5 seconds)

Since then the External Hard Drive has not been shown in Windows Explorer and in Disk Management is shown as "Unkown" and "Not Initialized"


The Drive will still be seen correctly in Device Manager and if uninstalled it will say it has correctly installed and is ready to use.


Attempts to recover data or Initialize the drive have not worked and I have followed and looked up multiple ways to recover and other similar cases. I'm fairly certain for the data recovery the drive needs to be initialized (which just throws me an I/O error upon attempting the process) as looking at the Volume section in the properties of the device the size of the drive is listed as 0Mb.


My Last resort is taking it to a data recovery shop and hope they can grab the stuff on there.

Any help is muchly appreciated thanks.

Answer:External Hard Drive Not Initialized

I'm not up on WD Elements. Did that HD come with a form of Smartware, and in that Smartware, was there a utility that would come up and either ask you to type in the user-assigned password or it would automatically type in the saved password and pass same onto The System -- and unlock the WD Elements? I ask because I'm a little familiar with WD Passport, not WD Elements.

Hi,

I am using Windows 7 Ultimate 64bit.

I bought a second internal hard drive about a month ago. I partitioned it and used one partition for Windows backup and the other partition is for storing data.

I moved a lot of data from my primary disk on to the partition on the new disk. Everything has been working fine until now.

This morning I booted up the computer and the new disk is not showing in Computer. I rebooted and checked the bios, the disk is showing there so I let the OS boot and then opened Disk Manager. The new disk is showing there too but now it appears as unallocated and not initialized.

How do I fix this and how do I fix Windows 7 so that it doesn't happen again? I really do not want to lose the data on the disk.

I have a problem with my external hard drive. The drive is Verbatim 47512. Last year I unplugged the drive without safely removing it first. When I plugged it in again it asked me to format the drive. As I didn't wanna loose my files I tried using Recuva and it worked. However, the process took too long and I was leaving for ten months the next day so I had to stop the process. I wanted to continue when I got back but the drive wasn't working at all. I couldn't even turn it on. I kept trying and after some time it started to work again. When I plug it in, I can't find it in my computer. But I can find it in the disk management. I'm attaching a picture, it says it's uninitialized and that it needs to be initialized. I don't know what it means and I'm scared it might delete my files. It also says that it's allocated and unknown. https://postimg.org/image/zci27fe6h/

Have a 1TB Iomega USB3 external hard drive that worked well on both a desktop and laptop Win7/64 system. Now it shows up as unidentified and not initialized using computer/manage/storage/disk management. Disk Management also gives the optiin to initialize it but I declined because I would like to recover the data. The power light comes on and it spins up with both a USB3 or USB2 connections and is identified as an Iomega eGo drive when I use the USB eject function.
Hard Drive Sentinel does not recognize it at all. Any suggestions appreciated.

Answer:Previously functional USB3 external hard drive shows not initialized

1. Please post a screenshot of Disk Management with your external HDD plugged in. Disk Management - Post a Screen Capture Image

Hi guys,

I was checking for errors on my WD HD the other day due to low speed and leave it alone but my mother unplug it inadvertently!

Clearly it's unallocated now. I've read a lot of posts especially those sent by jumanji (Windows 7 Help Forums - View Profile: jumanji) and apply almost all the steps. I've downloaded "MiniTool Partition Wizard Home Edition" and followed this thread: disk 1 is unknown, not initialized, unallocated

But the scanning speed was very low.I calculated the ultimate time needed to complete the scan with that speed rate. Guess what? 173 days

When I tried to format the Disk1, this window appeared:

Currently I'm following this post by jumanji (Regain a lost drive using Test Disk - An Illustrated Guide) and running the Testdisk, but the windows are quiet different. I'm not optimistic that whether it's going to work or not.

**I don't want my information back. I just want my External WD HD to be formatted.**

I'll be very grateful if anyone can help me, please

My English isn't very good. So I apologize for any grammar mistakes.

Answer:My external hard drive is unallocated

If you are not interested in recovering any data why do you want to run Test Disk/PhotoRec/Partition Wizard etc.,?

Please download and run Data Lifeguard Diagnostic for Windows WD Support / Downloads / SATA & SAS / WD VelociRaptor( Please read the instructions on that download page.)

Do a Quick Test and if it fails, do the Extended Test. If it fails the extended test also, RMA for a replacement if under warranty.

If bad sectors if any are repaired and your Disk passes the extended test, Write zeros ( you may choose a Quick Erase or Full Erase as you may wish but after the Extended Test a Quick Erase will do. If the Quick Test passes, you may skip the Extended Test and straight away do a Full Erase.) and then format the drive.

Answer:Unallocated External Hard Drive

If you want the data, you should make a copy as soon as possible.

A drive will be unallocated until it has partitions and a file system. Those can be damaged or lost by improper removal, such as powering off and on.

Then, you may want to run a diagnostic on it. You can find manufacturers' diagnostics here:

Ok, for my 2600k upgrade I backed everything up onto a data 500GB HD from my windows 7 Pro 64bit. Once my SSD came in I installed windows on it and then plugged in the 500GB data drive. Unforutnately it didn`t show up and I could only find it listed in disc management as a 500gb unallocated space HDD. Figuring this was something odd about it being plugged in as a secondary drive I put it back into the external USB drive but neither the new or the original system would recognize it other than in disc management as unallocated space. I went and plugged the external drive into my XP system...samething. Any ideas about how to get this data back. It`s very important stuff and I don`t want to lose it.

Thanks guys,

i am a beginner at this, i downloaded easeus todo backup and clicked on the clone wizard. i clicked on for the source hard disk which was 18.61 gb, next for the destination hd 111.79 gb , which was my usb storage device, next for the hard disk layout, i had 18.61 gb for ntfs ///93.18 gb unallocated, it also said dest disk will be deleted, but i guess i was thinking only the portion that was needed to copy the 18.61 gb would be deleted not my entire external drive, and it still did not copy my source disk. is there any way i can get my data back, please help.. thanks

Hi,

This is probably the silliest question ever, but I haven't done partitioning in a very long time and don't feel too confident, so here goes:

I bought a 3 Tb Seagate external hard drive a few years ago, created two partitions on it and left almost 1 Tb unallocated. Can't remember why, and didn't even remember it was there! All this time, I had been thinking I had a 2 Tb disk that was getting more and more full...

Anyway, I just rediscovered it and would like advice on how to best exploit it: should I extend "SeagBig" (which is full to the brim), or create a new partition (or several) in the unallocated space? What will be more convenient / less risky?

Also: I think I used Windows' own Disk Management tool initially. Can I do that again?

Thanks!

Answer:How to handle the unallocated space on my external hard drive?

You could make a 3rd NTFS partition; then you can either merge 2nd and 3rd partition or simply have 3 partitions. I think Windows' Disk Management will be fine. Scuttlebutt elsewhere indicates MiniTool Partition Wizard may be all you need -- or any similar 3rd party utility.

Using a new 6tb external hard drive plugged into a USB port for backup. Need to format but it only reads 1.5tb of unallocated space in Windows 10? Is this an Intel RST driver issue? If so, how can I tell if the RST driver need updating?

Windows 10 64-bit ver 1703 OS Build 15063.540
AMD 1700 8-core
Asus Prime X370-Pro MB

Answer:6tb external hard drive reads 1.5tb unallocated in Windows 10?

Try using diskpart. With the drive connected, open a Command Prompt (Admin) or Powershell (Admin) and run:

diskpart
list disk
select disk # <- replace the # with the actual number assigned to the 6TB external hard drive
clean <- this will completely erase the drive selected above, make sure it is the new external drive!
convert gpt
exit
exit

You should then see 6tb unallocated space in Windows that you can partition and format however you like.

Hello,
I have a Seagate 500GB Free Agent Desktop USB ST305004FDA1E1-RK, P/N 9NF2AL-570 that I was using to store my Acronis true image backups on of an older desktop pc. I had been having issues that the older desktop pc and wound up just doing a clean install and I was going to use my image backup from a few months ago to restore the pc to that time (only because I forgot about my image backup before doing the clean install).

I plugged the Seagate Free Agent External Hard Drive it into that pc the other day to restore it to one of those backups; it was recognized by the pc so I put the rescue / boot disc into the cd drive and restarted the pc. On restart It did show the screen for starting true image and then another screen popped up and vanished just as quickly and Windows XP Pro started instead. So I tried 3 more times with the same results. I then created another bootable rescue media disc and tried to load the TrueImage program but it again showed the True Image screen and then booted to Windows XP instead. It was late by then so I just shut down the computer and turned everything off and thought that I would try again the next day.

The following afternoon when I turned the computer on the Seagate is no longer being recognized by the computer. I tried plugging it into my laptop with the same results. It is listed in device manager and if I go to My Computer and right click for manage and click on disk management it is being shown but as unallocated space now.... Read more

Hello! Long story short, my external hard drive suddenly became unallocated. I've seen some youtube guides, posts on other forums, posts on sevenforums, but I can't figure it out -- the solutions for some of these forum posts don't work for me. And so I decided to make a new thread in the hope of solving it -- i've included details as specific as I can possibly remember.

Details:

I have a MSI laptop, windows 8.1 64 bit. Just today, while i was working my computer suddenly froze, and after a couple of minutes shut down. I couldn't boot up the computer as it kept going black screen, or the MSI logo booting screen (sometimes saying "Preparing automatic repair"). Then the computer went to install some sort of updates, and then crashed again. Eventually after numerous restarts/forced shutdowns the computer booted up fine -- except the external hard drive (built in the laptop) was missing. I discovered that the computer probably froze because a video recording software of mine was recording in the background and using up a enormous amount of disc space (40 gb video). After deleting the huge video file, the computer started working normally, but the external hard drive is still missing.

I've tried:

Answer:Laptop's built in external hard drive suddenly disappears/unallocated.

Welcome to Seven Forums.

1. I should first of all admit I do not understand what you mean by "an external Hard drive, built-into the laptop". An external HDD is one which is totally external to the PC and which we plug into the PC through the USB port.

Do you mean a second HDD inside your laptop apart from the system drive?

Please mention the exact model Number of your laptop.( So that I can check whether your laptop has two internal drives. I Know some do have.)

2. With such loose power connection inside your laptop, you are not going to get anywhere resolving the problems in the HDD. Since you say it is a new laptop, it should be under warranty and you should immediately get the problem rectified by MSI.

So please get it done first.

About 5 days ago my Seagate 3TB Barracuda HDD started running very slow. Transfer speeds dropped to 182kb/s it previously was around 25.6mb/s. So I started backing up as much as I could, but after 5 days and only getting about 300GB backed up I decided to run chkdsk on the drive. That was a bad idea because now I cannot access the drive at all, and I still have 2.12TB of data that isn't backed up.

Drive has been in use since November 2013
It had over 106,000 files on it.



Things that I tried before Chkdsk:

The drive letter used to be M:
In My Computer I had the drive renamed but it changed itself to local disk

Seatools - Passed all the tests when I was able to access the drive. But the drive info said the power on hours were 0 and the drive temperature was 32 degrees F, other external drives were showing around 30,000 power on hours and temperatures around 130-136 degrees F, the one internal drive showed 72 degrees F

Crystal Disk Info - Showed Unknown Drive and no Info

Crystal Disk Benchmark: Took a long time to run but I posted a screenshot of the results

Hi there,

So I had a desktop with a single HDD running windows XP, the desktop overheated and automatically shutoff. The next time I powered on the PC, nothing happened - no BIOS, no beeps, nothing! The PC was pretty old so I just figured it had run it's course and I was thinking about getting a laptop anyway.

So I got a new Windows 7 laptop, and after a few days of setting it up I yanked out the hdd from the old XP desktop and plugged it into the laptop's USB port via some SATA to USB cables.

Win7 recognized new hardware and and seemed to install the drive correctly as "USB Storage", but nothing ever appeared in the Windows Explorer. I opened up the device manager and under 'Disk Drives' I saw a 'USB Drive' item. The properties on that item seemed to indicate all the drivers and such were properly installed and the 'device was working properly'. Under the 'Disk Management' section, the disk showed up - but it said it was 'unknown' and 'not initialized', so no partitions showed up (it also prompted me to 'initialize' it, which I DID NOT do).

At this point I've tried several recovery programs, but the biggest issue is that none of the programs actually see the drive, so I can't run the recovery at all. I even tried Hiren's Boot CD, but again, nothing sees the drive - although, I think that I didn't properly install the USB drivers, so I may try that... Read more

I have a WD External SATA 1TB Hard Drive that has ~700 GB of family memories/movies/documents/etc and it is now connected to Windows 8.

The original housing it came in was unsurprisingly cheap and the connection piece broke. I re soldered it on and the connection was made but the drive threw nothing but errors. I figured I messed it up so bought an external case and assembled it. Now however, the drive does not show up under my computer but does in Disk Management.

Disk Management claims that the HD has the full TB unallocated and not initialized. I don't want to initialize it because I don't want to lose the information I have on it. Any idea on how to get this working?

I have downloaded and used the Data Lifeguard available at WD and the External has passed the Quick Test so drivers are all there and working.

Thanks
 

Answer:WD External Drive "not initialized" but has data on it?

Umm, I would try first connecting it back to whatever PC version you were using before (Assuming Windows 7) and seeing whats up.

If that does not work, try messing with the connection that you re-soldered and making sure its all done fully correctly, something may have gotten crossed.

That is bad news mate. Usually a mechanical HDD won't survive physical shock like dropping etc. This is because of the microscopical gap between the head and platter. Heads flying height on modern HDDs is about 5-10 nano-meters. For example: an average human's hair is about 25000 nano-meters in diameter. A drop will most likely cause the head to stuck on platter or cause scratches on platter surface.
I would suggest diagnosing the HDD using "Seagate Seatool" and verifying it's health.

SeaTools for Windows | Seagate
Run the tool and select your external HDD for testing. Then choose "Basic Tests --> Shot Generic" and wait for it to finish.

If the test is a pass, run "Basic Tests --> Long Generic". If either of the test fails, the case will be beyond DIY and you should consult a data recovery pro for recovery.

My scope is to save the content in the disk and move it to my PC, is it a mission impossible? Any suggestion is very welcome. Thanks Alex

Answer:Disk 1 Unknown, Not Initialized

I'm not sure you will have much luck if the disk is not readable. You can usually use a Linux distro to try to read it, but you've tried that. If it can be read you can also try Copy & Paste - in Windows Recovery Console. Other than that you could try Recuva and see if that will work. But, if the disk can't be read, I'm afraid there is nothing you can do if those 3 options don't help.

Hello,
New here to this forum. Been searching and reading for the past week trying to get my HDD to work.

I was able to access my external HD about a week ago, watched a movie off it and fell asleep. When I awoke the next morning, powered on my laptop, it wouldn't boot up so I shut it down and unplugged the HD and powered it back on. Plugged the HD back in, computer sees it but not showing in My Computer.

Within Disk Management, it shows Disk1 - Unknown - Not Initialized.

Searched and searched and searched for different solutions, tried different things and still nothing. I have tried PW but not showing up to be able to scan it. I have a docking station so I pulled the HD out and plugged it into that. PW was able to see it but no partitions found. Tried to run TestDisk (per some other help treads instructions) with nothing found.
I have ran EaseUS recovery, recovered some files but none which were readable.

I have lots of important files on this HD and I really need them. Sending it to a professional is out of the question.

I'm currently about to boot up pendrive and see if it sees anything there.

I can post any screen shots and try anything again. I have done nothing but scans scans scans.

Thank you!

Answer:WD My Book 3TB Ext HDD - Unknown - Not Initialized

Hi HAPPYSOk,

Welcome to Seven Forums.

I would have been happy to help you had it not been a Western Digital External drive.

Is your drive's model No. this WDBFJK0030HBK?

Your drive is hardware encrypted and should the interface card that contains the encryption chip and the decryption key fail, even if the HDD itself is good, you can't get your data out by hooking it up as a second drive in a dock or sata connect on a desktop. You can get what data is there inside but it will be the encrypted data.

Your statement "I have ran EaseUS recovery, recovered some files but none which were readable." confirms this.

The only way you can get your data back is to send the enclosure and drive to the Western Digital patronised Data Recovery Partners listed by WD here WD Support / Data Recovery Partners. Only they have been supplied with the decrypt key by WD and they will do it in a jiffy for you.

Free consultation, So get a quote from them and you will never again buy a WD drive, I am sure.

This 2.5" SATA drive is from a Toshiba that seems to have died this morning. There's no boot, no BIOS, nada.
I removed the drive and attached it via USB to my Win7 box where it shows as "Unknown, Not initialized, and offline." There are no rt-click options in disk management. I can hear the drive spinning, but it shuts down on its own occasionally, and sometimes won't power up at all without a bit of fiddiling.

Is there anything else to do, or is this drive dead, as I suspect it is?

I am trying to recover data from laptop internal HDD use as an external hard drive to recover data from that HDD. I can't see my HDD in my computer but in DISK Managemnet, there is a message, "Disk 1 Unknown Not Initizalized"

Please Help!!

Thanks,

Answer:Recover Data from Disk that is unknown and not initialized

If the data is critical, and it sounds like it is.. the first thing I would do is use a software that makes a sector by sector backup or image of that uninitialized drive. That way if trying to make it readable by initializing it should hose it, you have a copy.

After that, if you know that the unititialized drive was at one time formatted NTFS then you might try initializing it with Partition Wizard freeware

But it may be worthwhile to talk to someone well versed in disk recovery. There may even be some dedicated forums around for that specialty.

If you get lucky and the Partition Wizard initialization shortcut works, then the files should be there after doing a non-destructive format as NTFS file system.

Assuming that's what it was to begin with.

It means the disk surface is severely damaged (has developed pretty huge number of bad sectors ). At this point, Imaging the disk and working on the copy is the best step you can do. I would suggest ;

- Create a RAW disk image using "ddrescue". Since your HDD is a 2TB one, you need a larger capacity drive like 3TB one to store the image.

- Try the trial versions of "GetDataBack" and "R-Studio" on the RAW image. Both supports working with disk images created by "dd" and "ddrescue".

Answer:Disk unknown, not initialized, and not showing partition

Hi

For any serious troubleshooting, diagnostics or recovery attempt, you should always connect an HDD to a direct SATA port. Usually you can easily remove the header of any Seagate Golex drive and then connect it to an internal SATA port.

Let us know what "Disk Management" reports when you connect the drive directly.

I had a Seagate drive fail suddenly last week -- a lot like the situation you described, and neither the Seagate nor the WD drive diagnostics even see the drive when it's in an external drive caddy. When I connect it to an internal drive cable, I get a SMART error and the PC hangs on the boot.

Have also tried Minitool Partition Wizard and some other data recovery apps, which CAN see the external drive, but they can't find or recover any partitions.

Suggest you check with Minitool as they offer a free trial of a data recovery app that might work for you.

This is the first time in years that I've had a drive fail and NONE of the data recovery apps have been able to find anything on the drive.

I've resorted to sending it off to a local data recovery service and am awaiting a quote.

Now if I delete the drivers it appears in Disk Management as an offline and not initialized drive, no drive letter. I can't initialize it and trying to set it to Online results in an an I/O error. When i unplug it and plug it back in Windows appears to be reinstalling it, but then it's back to not appearing in Disk Management at all.

This occurred when it was just Win 8. I upgraded to 8.1 and it worked for about 8 hours. The drive installed and functioned 100% after upgrading to 8.1.....and then just stopped working again. Same issue. Again, the drive works fine in every other computer I connect it to. Every other drive and USB device works fine when connected to this tablet. Just this one drive on this one tablet refuses to initialize.

Any ideas?

Answer:Wd External HDD Not initialized

Tablet might not have enough power thru USB, smaller devices could work and this one is probably pulling too much. If that's the case you can connect it thru an USB splitter with it's own 5V power supply but that won't make it as portable.

Hello

I am trying to recover data from my external HD 1 TB Fantom Drive GreenDrive. It crashed and I had no choice to force power down. When I look into Disk Management - I see that Disk 1 Unknown Size Not Initialized.

See Disk Man.JPG for printscreen of Disk Management.

I tried following the Mini Partition Tool advice and did not find the external drive on the software. Please see Mini Partion Tool.JPG for print screen.

I am thinking about buying another external HD 2TB and clone this drive to recover the data. Any advice to clone a drive that I cannot select.

Thanks in advance for your help!

It crashed


I've seen that and the HDDs had truly crashed, wasn't anything I could do but in a couple of instances I sent them off to a firm that recovers data if the platters/disks in them haven't been physically damaged. Sometimes the read-write heads will scratch the platters and they are then truly screwed up.

Hi,
 
I'm not even sure what the topic title should be. But I can tell you about my problem.
 
I plugged in a new Bipra 250 GB NTFS external Hard Drive with the intention of using it to clone my C Drive.  A scan of the new drive reported no errors.  However, when I tried to run AOMEI Backupper it quit with this message: 
 
Information Code:4120 
Failed to adjust partition size.
 
Although I could see the drive when I clicked on Safely Remove Hardware, I could not find the drive in Explorer.
 
In Device Manager the disk was listed as Mass Storage Device USB Device.  I tried updating the driver, but MS says the driver is up to date.
 
In Disk Management, the disk showed  as Disk 1  Basic Online.   232.88 GB  - Unallocated. 
 
Online I found information that said to right click the drive and choose New Simple Volume.  I did that. It ran. Still the drive goes unrecognized and I am unable to clone it. 
 
I tried a reboot with the drive plugged in.  When Windows started, I could see the drive in Explorer but a message said:  Location not available.
 
Well, dirty word. -- And now that is gone too and the drive once more shows as unallocated in Disk Management.
 
More info online tells me to partition the drive after running New Simple Volume. But now I'm afraid to do that, and I don't know why that is necessary.

Answer:asNew external HD not Initialized?

Can you post an image of Disk Management with the USB drive attached?
 
Edit: You can use Partition Wizard to create a partition in the unallocated space and format it NTFS.

I have an external hard drive from home (160 GB iOmega) formatted in I believe FAT32 with all my data on it from my iMac. I'm trying to connect it to my new ThinkPad to get my data. It doesn't show up in My Computer, but in Disk Management there is a Disk 1 that has a black bar at top instead of blue, says not initialized on the side, and says unallocated under the bar. Also, when I open Disk Management it offers to initialize my disk, but I fear that would erase my data.

How would I get my computer to read the disk but not erase my data?

I have a 300GB usb external hdd, when I plug it in it beeps but does not show in "Computer". I right click on Computer/Manage/Disc Management and it shows there as 298GB Disk 2 Not initialized. A box appears, saying you must initialize before Logical Disk Manager can access it. When I click on OK I get the message Data Error (Cyclic Redundancy Check)
If I go to the box to initialize it everything is greyed out.
There is nothing of any importance on the drive so if everything is lost it doesn't matter.

Any solution do you have for this?

Answer:WD External HDD 2TB not initialized I/O ERROR is it dead???

Hi, papaikolaou1980. Welcome to Major Geeks!

Unfortunately, none of the screenshots are showing here. But, if you've done everything listed in your post and the drive isn't showing properly, I'd say it "died" and if still under warranty, you should get a replacement. If it's a "green" series rather than "blue" or "black", I'd avoid getting another one as there have been many dependability issues with WD's "green" series.

Hi,
I have an WD Elements 1023 external hard drive which I want to connect to my laptop which runs a 64 bit Windows 7 Home Premium. When I connect the device, it shows up in the device manager and the driver is installed properly.
However, it doesnt show up as a drive and in the Disk Management, it shows as Disk1 unknown. When I try to Initialize the disk, I get a error that the "The Media is write protected".
Its been a real pain as I have a lot of data init and unable to access it.
It wud be great if anybody could suggest me a solution for this.

I have an WD 1TB hard disk which failed to initialize recently. It gives me an I/O error message. I found a few old threads here with similar problem and tried out the suggested steps. I ran WD diagnostic tool and passed the Quick test and Extended test(Screenshot attached). I would like to avoid the zero test and formatting of my data if possible. The hard disk is almost full and recovering them after formatting would be really painful. I would be really grateful if someone could please help me out?

Answer:1TB WD external hard disk not initialized

Is you have a empty hard drive kicking about or somewhere to store you data, move it all to there.
Then format you drive, see if that works.

I have this WD 1TB external drive that stopped working a while ago. I am trying to initialize it in order to perhaps try to recover data from it using a Data Recovery Wizard.

When connecting the drive via USB, it only sometimes shows up in 'Devices and Printers' as connected through USB (ie, it allows me to click 'Eject My Book' in the task bar). When it shows up there, I can also see it in Disk Management as 'Disk 2, Unknown, 931.51 GB, Not Initialized' with a little red downward facing arrow icon.

When I right click the icon (with the red arrow) and choose Initialize, it hangs a bit and then shows an error saying "The request could not be performed because of an I/O device error"

When I run 'USB device viewer' (UVCView) this is what shows up next to that device :
