Disk unknown, not initialized, and not showing partition

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

I am experiencing the same issue as with jenny123 but with an additional problem. I am troubleshooting a Seagate FreeAgent GoFlex 1TB external hard drive for my buddy. It is previously working but one day, it is not detected anymore by any device. It is found in the Disk Management however, it is listed as Unknown, Not Initialized, and not showing the partition as shown in the screenshot.


When I try to change it from Offline to Online, I am encountering the error:
"Virtual Disk Manager: The system cannot find the file specified"

I also used the DISKPART in cmd but it is not showing Disk 1 as shown below.


The external hard drive is found in disk drives but it is not showing it's model name.


I tried all the recommended software (partition wizard, testdisk, icare) but still no luck. I also tried searching online for an answer but there's no closure to their issues as well. Hope someone can help on this as he need a) the drive and b) recover the files in the external drive. Thanks!

EDIT: The drive can be seen in the Devices and Printers as shown below.

Preferred Solution: Disk unknown, not initialized, and not showing partition

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: 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.

Hi, I just got a new Y570 Laptop with a 64 gb ssd. In the disk management window, there are two hard drives listed. There is a disk 0, which has four partitions on it, and a disk 1 which is unknown and initialized. Disk 0 is the HDD that comes with the computer. When I try to initialize Disk 1, I get a message saying The disk cannot find the sector requested. What does this mean? Also, is disk 1 the ssd that I'm supposed to have? Another problem:On my hdd, I have an empty partition that says Healthy (OEM partition). It has no file system or letter assigned to it. It is 14.75 gb, and according to disk management, all 14.75 gb are free. What is it, and can I delete it without affecting anything else on my computer?

Answer:Y570 Unknown Disk 1 Not initialized/OEM Partition

hi galaxion2,first of all, do not delete the 14.75 gb partition. it's hidden/system partition that your computer will need to use it during one key recover process.secondly, as you noticed, disk1 is ssd.

Hi Jumanji,

My external HDD (WD) is not getting recognized in my laptop from last few weeks. I have followed different threads but didn't get any working solution.

I have tried below options:

1. Disk management : Initially showing MBR/GPT options but none worked. After that its showing my external HDD as 'Disk1 unknwon not initialized'.

2. MiniTools Partition Wizard : Installed MiniTools Partition Wizard v9 in my laptop however my external HDD is not showing in the tool as Disk2.

Could you please help me to get the issue resolved or recover the data at least.


Many thanks !!

I can?t find the drive in my computer but I can see it in disk managment. It says Disk unknown - not initialized.

I?ve tried using PW but i cant see the drive on there. I would really like to keep my files I have on that drive but it seems to me that it toast.

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.

Hi, My DVD Recorder died, so I took out the HDD Seagate DB35.2 and plugged it in my laptop. I get the above message in disk management. I also tried Knoppix 7.0 but the disk does not show up. 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.

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.
I can't get any response at all from my Linux box, and neither Test Disk nor Recuva finds it at all.
Is there anything else to do, or is this drive dead, as I suspect it is?
 

Answer:Disk unknown, offline, not initialized.

If it's not being recognized properly, there isn't anything else that you can do.

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.

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.

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.

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.

Many thanks in advance.

Fido.

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. Now when I right click the option to Initialize Disk is grayed out and I can only see Offline and Properties.

I browsed through a thread from about 2 years ago and couldn't find a helpful solution.

The drive: Western Digital 250GB SATA / 16MB Cache - WD2500AAKX

Answer:Disk Management - Unknown / Not Initialized Drive

Have you attempted to run Western Digital's Data Lifeguard diagnostic software? It has a short test and an extended test.

Are you trying to recover anything from this drive? Or just trying to find out if it's broken?

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 am using windows 8 and I have read previous threads with similar issues that I face but my problem is unique. My 60GB external Hard disk was manufactured by FUJITSU and was taken out of a dell laptop. When I bought a case for it yesterday it was tested in a laptop computer to see if it was working before I paid for the case and it was working properly. However, the owner of the laptop removed the cable without safely ejecting the drive first. 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. In disk management it is shown as Disk 1 unknown not initialized as shown in the attached screenshot.

I notice that whenever i open disk management, it prompts me to initialize the disk but when i chose gpt and click ok, this window pops up

when I right click the Disk 1 the initialize option is gray and only offline, properties, and help are available. I used mini partition tool and this is what i get

I am at my wits end. Please assist. I do not need what is inside the hdd. I just want it to work.

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.

I have this 160GB hard drive that I have not been using for a while, yet I am very sure it was working fine the last time I used it.

Today when I plugged it in to my new notebook that is running Windows 8.1 now, it doesn't detect my hard drive. I also tried on other notebook and it has the same issue. So I know the problem is most likely on the hard drive.

Using Command Prompt, it says Disk 1's status is "Online", but size is "0".

Here is the status at Computer Management:
Disk 1
Unknown
Not Initialized

I also tried to Initialize on MBR, but it returned me with "Incorrect function." message.

I tried "Troubleshoot" and the result says:
"USB Mass Storage Device is an older USB device and might not work with USB 3.0
Plug the device into an available USB 2.0 port..."
My notebook has 3 USB ports where according to the manual, 2 of them are backward compatible to 2.0... I tested on each, but it is still not working.

What should I do? Although I have not been using it for a while, I wish to check the content first before formatting it. I might have some forgotten, yet important files within.

Thanks in advance. Hope I can be assisted here.

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.

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.

The WD tool will list both your internal HDD and USB HDD for testing. Select the USB one and choose "Extended Test" to run. Let us know the test result in next reply.

Issue is with my sisters External Hard drive, a WD My Passport Elite 070B.

Downloaded PW Minitool Recovery and EasyRecovery Pro Trial, but haven't really run any lengthy tests yet. Just tried them out for 10 mins to see if anything would show up. Going to leave the computer on tonight and do a full scan though.

Some other things I have tried:

-Tried different USB cables

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.

My PC wouldn't boot off the SSD (with Win 10 OS). It said there were boot problems and tried to diagnose the problem but it doesn't boot. I'm now using the original HD with Win 7. I'd like to get the SSD working if I can. The SSD is OCZ - 240 GB or so.

But between last night and today, the SSD has gotten worse. I can't access it at all now. Last night I was able to access it as an external drive. What I did in between was a chkdsk of the HD just to make sure it was OK. Then this morning I saw that the SSD had problems.

Disk Management shows the SSD as disk 1, but it has no information on it. It just says the disk is unknown and uninitialized.

I saw a recommendation for Partition Wizard 9.1 Free. But that doesn't show the drive at all. I attached screen shots as a Word document.

Any help would be greatly appreciated.

I believe i was attacked with a virus that messed up my OS booting. The Blue screen pops instantly after the attack. I restarted and the Blue Screen pops up again. I tried to load it with the settings that worked and the blue screen came up once again. I tried safe mode as well and still no change, same blue screen. As usual I thought a reformat would do the trick.I booted with my winxp cd and wanted to reinstall a fresh copy and i saw

Unknown Disk
(there is no disk in the drive)

Unknown Disk
(there is no disk in the drive)

I restarted the comp and rebooted with the cd and i ran the Repair Console
I typed in fixmbr to fix the issue. But the same Unknown Disk was still there when i tried to reinstall again. I did a chkdsk with Repair Console and the ' The Volume appears to contain one or more unrecoverable problems' msg appears.

I'm lost with what to do now

Hi.
I have a Seagate Goflex 500GB external hard disk. When I connect it to my laptop, it doesn't appear in my computer, and I have attached the screenshots of Disk Management and MiniTool Partition Wizard.
The hard disk is behaving this way when I removed it from my laptop while it was copying a file.






I do not need any data. I just want my hard disk to start working again.
Please help. Thanks in advance! High hopes!

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

I plugged the drive into a laptop, had the same results

I tried replacing both the power cable in the USB cable, same result

I tried plugging the USB into a USB 2.0 port instead of the 3.0 that it had been in, still the same exact transfer speed

I tried changing the HDD's policies to Better Performance instead of Quick Removal. Same 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

Answer:HDD - unknown, not initialized

Does this drive spin up at all? Listen carefully for any "clunk" noises. It may well have died.

The computer[nt4.0 server with service pack 6a] was running fine with two physical hardisk both running on ntfs. Later when I installed the the modem i just couldnot install it. The modem was not detected and the system just stoped booting also. I installed a fresh nt 4.0 on the same primary hardisk formating it as fat. Instalation is sucessful. But the operating system cannot access the secondary hardisk which is ntfs. The disk manager shows the disk but says "partition unknow" although it is ntfs. When i open the file manager and try to access the secondary hard drive it says "drive is not readable. disk structure is curupt and unreadable".When I right click on the drive and i hit properties i do not see the sercurity tab. Since I have reinstalled the operating system the service pack right now is service pack 1.
I want to recover data from the secondary hardisk which I can not access please help.
 

Answer:ntfs partition is unknown by disk manager

Did you overwrite your original install? If not, you may be able to repair it. I would try to convert the current partition to NTFS, but that may not help. Partitions created by disk administrator can be difficult for another OS (other than the one that created it) to work with. You may be able to save the data using ghost to take a picture of the second partition, then wipe it out and re-create it and use ghost to replace the original data. That may work. Hope it helps.

Hi

I have a two laptops with Windows 10 x64. Recently I noticed new partition with next available letter. Size is 128mb and it can't be accessed. I checked in Disk Management but this partition is not listed there as per the below screen:

I used MiniTool Partition Wizard and managed to see details about this partition.

I tried Diskpart to remove Drive Letter but no luck:

This happened at the same time on my two HP laptops but not sure what could cause it. Maybe some Windows update? I do not remember installing any new apps. I would like to remove this disk from the list of available disks.

Can anyone suggest/advise how I can remove this from the list?

Thanks

You never selected the volume so you can't remove the drive letter assignment - that's what the command response tells you. do a "list vol" to show list of volumes and confirm its volume number then do "select vol ___" (insert volume number) to put focus on that volume and then "remove" should work.

This appears to be your MSR partition (apparently created in Win8/Win8.1 install before upgrading to Win10). Should not have a drive letter at all.

Do you know that you are booting OK in UEFI mode ? It certainly looks like you have a GPT disk, although it's a bit mis-mashed due to upgrade process.

Hello there. This is my first post at this forum.

I have a probably 6-7 years old WD Elements 1TB external HDD. When I connect it to PC via USB I can hear ordinary HDD detected sound and after that it sounds some short beeps at 7-3-3 order. Here are some screenshots of my situation. Is there any way to recover my data stored in this HDD? My priority is saving my data but saving HDD would also be cool

how can i solve this problem

First thing I'd do is try to run the hard drive manufacturer's disk tools on the drive. It may be dead or dying. Shows as "bad disk" with no file system in PW.

And I'd hope I had a backup of whatever is on it.

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.

Hey all. I just got a new SSD to install into my laptop. Toshiba Q Series Pro HDTS325XZSTA 2.5". I bought an external casing for the HDD for when I replaced it, but to clone the Laptop software over, I have the SSD in the external case for now.

When I went to Disk Manager to get it setup, I right-clicked and initialized it under MBR. It's assigned a drive letter. However, it shows No Media and a size of 0, both on my PC with USB 2.0 (Windows 7) and my laptop USB 3.0 (Windows 8).

I have plenty of time to return this drive for a new one if that's the case, but I want to know if I'm doing something wrong before I go through that process. I've never had this kind of problem before.

Hello. I am trying to reformat my computer and I have ran into a problem. i have tried to reformat using both Windows XP Home and Pro. When I pop in the CD and Boot from it all goes well until I reach the Partition selection screen. Instead of the list of drives and partitions I see this message in the box. It is repeated four times.

Unknown Disk

<There is no Disk in this drive.>
I am confused by this and i am not sure what I should do. i was thinking this could be caused by the fact that the necessary drivers are not present when I try to reformat, but if this was the case wouldn't I get the message before I even got to the Partition Selection screen? That has happened before and simple slims stream of the appropriate drivers fixes it just fine. So would a slipstream of the drivers fix this problem as well? I am hoping someone knows how i can fix this problem and have a successful reformat. This problem is on an HP Pavilion a1530n running Windows XP Media Center Edition. Thanks in advance.

Did you initialize that partition before you put data on it. But if you want to do it now, save your data first. Try using a live Linux distro. That may work.

Who knows what Partition Magic does. That is an old defunct program that has not been updated in 5 years. Next time use Disk Management or Partition Wizard.

I tried to connect an external drive that wasn't showing up so I went into Disk Management and tried to enable it. I was not able to get the drive to work on this laptop but now when I look in Disk Management, it's showing a volume for a 12GB hard drive that is not connected. In addition, to the right of Disk 0, it shows 3 partitions now. The first is the 12GB  "Recovery Partition", then the 102MB "System Reserve" which is normal and then the C drive which looks normal.There is no 12GB HD connected to this laptop. When I right click either on the volume on top or the "partition" below, it doesn't give any options besides "Help", which is pretty useless.Here is a screen shot:Any idea how to delete this volume/partition?I tried system restore, by the way. It didn't remove it.

Answer:Disk management showing volume/partition that does not exist.

You say you believe the 12GB partition/drive should not appear in Disk Management, yet it's clearly labeled Recovery Partition.  So, the 12GB partition is the Recovery Partition put there by Acer and it's there in case you need to restore your system to it's original configuration.  This, i.e., a Recovery Partition,  is standard on practically all computers on the market in recent years.  And, if you use the Recovery Partition to restore the system, the Recovery Partition will continue to exist after you've done a restore. So, based on your post, I really don't see a problem.  Can you re-state or clarify what you feel is the problem?

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.

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:

- booting in ubuntu and knoppix via cd - drive is not recognized

- every major app for this type of problem i saw recommended: seagate seatools, partition wizard, wd data lifeguard diagnostics, power data recovery, find and mount, a bunch of stuff on hiren's boot cd, test disk, etc.

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 try... Read more

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!

hello there ,
i have a Toshiba hard drive 500 GB it was working fine but suddenly when i plugged into my laptop i discovered it is not working and when i go to disk management it said Disk 2 unknown and not initialized.
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.

One fine day Win 7 displayed "Do you want to scan & fix removable drive G:" prompt. I check marked both subsequent boxes on the prompt and clicked Scan & Fix. After complete execution of the Scan & Fix (after 12 hrs approx) my Portable 1TB WD Elements SE was shown as Unallocated, Not Initialized & Unknown in the Disk Management and clicking on it windows explorer My Computer window showed the HDD with a Letter but on clicking it an error pop-up with text "Drive G: is inaccessible.

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".

I have Partition Wizard 9.1 and the attached picture below is the screenshot of the main GUI. It shows bad disk on the particular hard disk
I tried running Partition Recovery Wizard on the mentioned HDD and it shows a partition of only 512 Bytes but none of my files are visible (no preview)

I just need to retrieve the files in the Hard disk as it contains important files and pictures that havent been backed up. Any help and suggestions are welcomed! Thanks

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!

Found other posters here with the problem which led me to post. It was working fine and due to whatever it now doesn't show up in explorer.

Shows up in device manager and shows up as usb. I can't get it to view in partition wizard or any other recovery program like testdisk that tries to view it.

I currently have it out of the case and attached internally. I had to add it with computer running since I can't access any jumper settings and computer won't boot with it installed.

BUT it shows up in disk management. Images attached.

Though a restart might help but now it doesn't read at all. In Disk Management it says that disk says "Disk 1 not initialized".

It means that Windows somehow failed to recognize the mbr (its signature) as being valid. Initializing the disk will (try to) overwrite its mbr. The partition table is usually stored here.

Can anyone help please..?? urgent..

Answer:Disk not initialized message

Sounds like your disk has become corrupted, or has otherwise failed. Disks are notorious for failing, just when you think that they are "running well". The only answer for data redundancy is RAID 1 (or a derivative), plus backing up to an external hard drive.

I suggest using some sort of Partition repair program in an attempt to rebuild the disks "Index" thus potentially allowing you access to the disks contents again. However this sort of activity is risky, either you will fix the partition or make the situation worse, in my experience the outcome is usually 50 / 50 - sometimes things end with a smile, and other times a tear!

Best of luck...

The disk had never been used prior, so he had to initialize it when I brought it over; he's running either Win8 or Win8.1, and it was initialized as GPT with all the other settings at default. It was hooked up via a SATA > USB 3.0 adapter.

I brought the disk home and plugged it directly into my mobo, and Windows was telling me I had to initialize it; without thinking I clicked to initialize it as GPT, and haven't yet created a new simple volume.

What I'm wondering, is if there's a tool (preferably free) I can use either in Windows or a bootable linux distro (the Ubuntu I have doesn't have drivers for my USB wireless adapter, so I'm without internet whenever I boot into it; therefore the distro will need to come with the tool pre-installed) which will be able to copy the data from the used sectors to the unused ones within the same disk, so I don't need to worry about overwriting the data I'm trying to recover. I'd like to do it this way because each of my other two drives have 14.5 and 44 GB free, so I can't recover it to another drive then copy it all back

If there aren't any tools that do that, any suggestions other than bringing it back and copying the data again? (it took pretty long and was a bit of a pain, plus he's leaving for a week in a couple days.)

My set up:
Win 7 x64
1x ocz 128GB ssd
1x seagate barracuda 1TB hdd
1x WD black 4TB hdd ... Read more

Not sure I understand your situation and I don't think I ever heard of such a tool.

I'd think in terms of partitioning the disk and putting all the data in one partition to shield it.

Why GPT?

This is purely a data disk, no OS?

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.

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.

This drive was originally a Maxtor back-up drive that my brother in law could never get to accomplish a successful back-up routine when running on his XP desktop system or his new Vista laptop. He gave it to me and I installed upgraded software and tried it on my Vista x64 system and again recieved "back-up failed" error messages. I decided to delete all contents on the drive and use it as a basic external storage drive. My problem is now my system see's it as "Drive not yet initialized". How do I initialize this drive?It's a Maxtor One Touch III, 200 Gb.

Answer:WD extrnl drve not initialized in disk mgmt not shown in my comp

Hi there, this drive is power fed trough the USB cable. So if the cable is damaged or too long it could cause the drive to malfunction. Otherwise it could be a damaged partition or a failed drive. I hope it will be a power issue, as it will be easier to resolve.
Have you tried:
- using a different USB cable (the shorter the better),
- connect it to a different usb port on the PC and make sure all other usb fed devices are unplugged at the time;
- if it's a desktop make sure to use a usb port that is on the back of the PC.
- connecting it to a different PC with a different OS

It will be useful if you give a bit more information. Can you hear any unusual noises from the drive? Have you dropped it recently? Do you remember making any changes before it stopped working ?

I had this flash drive since last year. I always download movies, t.v. series and anime. After I have watched all that I have downloaded, I always delete it and it also appears in the recycle bin so I also deleting it to not waste memory.

Last March 27, after I download and move the files in my USB. When I went back to my renting house, I tried to watch the t.v. series that I have downloaded in a DVD(XViD format). Unfortunately, the DVD can't read my flash drive.

I attached my USB to a computer and then suddenly, it was not detected by Windows Explorer but appears in Disk Management saying that it is "not initialized, unallocated drive."

I do Google searching and I found this forum, I found out that I should use a partition recovery software. I tried but when I scanned my drive, it always stops at "7-8k of 62530624 sectors." I don't know why but I think my flash drive was damaged.

Is there any other way I can fix it?
My important files are inside there.

Hope that any one can help

I was in the process of updating several sata controllers and chipset drivers. I also installed a new USB 3.0 hub and was in the process of moving around several devices between ports. I had a problem with my keyboard which uses USB 2.0 as a connector but I would recieve a "Unknown USB Device (Port Reset Failed)" code 43 on every port on the USB 3.0 Hub. I finally gave up and put the keyboard back into the 2.0 ports on my motherboard. When I finally fixed everything. I realized my DVD drive was not working. I had to reconnect the SATA cables because it got disconnected while I was moving my PC around. Upon the last restart of my PC.

I checked Disk Managment and noticed lots of system reserved partitions and drives which were not there before. I have no idea what happened but I think updating several drivers and the combination of reinstalling USB ports via device manager or the optical drive being reconnected may have messed up how windows used to have system reserves as partitions. I only had one visible system reserved drive before, now I have 2 visible and lettered system reserved drives.

I also have a unknown partition at the top of the list, I cannot right click that partition and select any options. The only option in my context menu is Help which brings me a link to Overview of Disk Management

I also had my video quick access as my DVD optical drive when I restarted. I have fixed this issue by changing my quick access links back to their proper folders... Read more

Answer:Unknown Partition - Unknown File System - Cannot edit or remove!

Hello taqiyya6 Welcome to the Ten Forums!

Your problem is actually quite basic. You are going into the Disk Managetool and seeing system reserved partitions mounted and assigned drive letters where they shouldn't be seeing any! The 450mb partition is there to allow changing from the MBR type primary to the GPT type usually seen with server set up or large volumes exceeding 2tb in size such as installing and partitioning a new 2.5tb, 3tb, 4tb, or even one of the latest 5tb drives.

The sight of the System Reserved partition being present on the second Disk 1 500gb drive simply shows that had previously seen a Windows installation on it at some time likely before adding in the large 1tb Disk 0 drive you have the present install on. The most likely to succeed option for taking care of the smaller 500gb if nothing is on it would be a complete wipe and a fresh single partition intended for storage and backup. That would eliminate the first SR but not small second unless using an open source type partiioning utility like GParted while still an option to close up the small gap since it is only a 500gb and not exceeding the 2tb mark.

For cleaning the mess overall however going into the Device Manager and knocking out drivers before a full restart would allow Windows to redetect the drives fresh without seeing the System Reserved and MBR parts mounted again at least on the OS drive being the main concern since the SR part has to remain invisible as a system protected space not mount...
