hard drive w/ usb adapter- drive shows in disk manager, not computer

Question: hard drive w/ usb adapter- drive shows in disk manager, not computer

I am trying to access files on a hard drive from a different computer which will no longer load the OS. I have connected the hard drive using a usb adapter. When I plug it in, I get a notice that the device is ready to use, but it does not show up in Computer.

It is visible in the disk manager. There is no drive letter assigned and the options to do so are grayed out. Most of the options in device manager are grayed out, except for 'delete volume' and 'help'.

I have an external hard drive that wasn't showing up anywhere on my computer, so I replaced the hard drive case and now the external hard drive is found in device manager, but not in disk management or my computer. I am running windows 8, and there is data on the external hard drive that I would like to have access to.

The disk drive that is in the case is a Samsung HD103SI

I have used the rescan command in disk management. It showed as Disk 2 Unknown and not initialized. (Please note this is not a new disk and it has data on it that I am hoping to retrieve).

Some information that might help:

The system is:
LENOVO 90B70019US Lenovo H50-50

Using Belarc Advisor the drives show as:
MATSHITA DVD-RAM SW840 [Optical drive]

ASMT 2115 USB Device [Hard drive] -- drive 2, s/n 00000000000000000000

Any help would be greatly appreciated. Thank you

I have a problem with a new external hard drive I bought. In Windows XP, it appears as "Seagate Expansion Desk USB Drive" under Disk Drives in Device Manager, but it doesn't appear in Disk Management, where all the drives are listed. It also doesn't appear in My Computer. How can I allocate it a drive letter so I can use it? My drives go up to K, so it should be allocated L drive. Any help would be appreciated.

Answer:Seagate External Hard Drive shows up in Device Manager, but not Disk Management.

Attach the drive to a different usb port. Open a command prompt. Type

I've spent most of the night searching and cannot seem to find an answer to my problem so I registered with the hopes that someone here may be able to help.

I have a NAS set up with two 2TB Samsung Spinpoint hard drives. The hard drives in the NAS were partitioned to have 300GB in a RAID 1 and the remainder in a RAID 0. One seemed to be failing so I removed it hoping I could connect it externally to my laptop and recover the data. When I hooked it up to the laptop, it seemed to connect fine but did not show in My Computer. When I went to Computer Management - Disk Management, it shows the partitions as healthy (see image - Disk 1). However, when I right click on the partitions to assign a drive letter, the only options available are Delete Volume and Help. Same when right clicking the Disk 1, all that is available is Convert to Dynamic Disk, Properties, and Help.

Any help would be greatly appreciated. Thank you.

I have a Western Digital 250 GB external HD that had been working perfectly until yesterday afternoon. It has been making this repetitive whirring noise *not the clicking noise of death* and it died before I had a chance to copy the data onto another external. When I plug in the USB it makes the connection noise, but autoplay does not come up and it does not show up in my computer anymore. I did look in device manager and disk management and it does show up but it had no drive letter and it says unreadable. (I've attached a screenshot of this)

Is there any way I can recover the data off of it? Should I just take it out of the enclosure and hook it up to a desktop pc?

Answer:External hard drive broken shows up in device manager but not My Computer

It sounds like the drive itself is dead rather than the enclosure. The repetitive 'whirring' noise likely is immediately following the click of death, just the click is pretty quiet on a lot of notebook drives. If yours is a full size (3.5") drive in that enclosure, then perhaps you are right and the click of death isn't occurring.

In either case, its not going to hurt to hook it up internally, because even if it doesn't work you aren't any worse off than you are now.

Hi there,
I've been having a hard time with my secondary hard drive showing up when I go into the "computer" option under my start menu. It does appear under Device Manager though.
I've reseated my cables numerous times, purchased and used new Sata cables, and I'm also running a new motherboard. I've also changed and disabled all my sleep options already.
I recently switched to using a Primary SSD for my programs to be installed on but ever since switching over to my SSD my HD no longer appears and I can't save anything to it.
Any advice? Thanks.

Answer:Secondary Hard Drive Disappears in 'Computer' Shows in Device Manager

You seem to need to assign the drive a path. Do this:
1. Open the windows search bar by pressing the windows logo in the bottom left corner of your screen
2. Search disk
3. Find the option labeled Create and Format Hard Disk Partitions
4. Select it
5. Find your hidden disk
6. Then assign your disk a path and it should appear in My Computer

Hope I helped!

...It initially didn't show up in 'Computer' (or My Computer). Device manager said its working properly.
I put the Vista Disc in (had to get a pirate one from someone because my disc drive won't read the official one all of a sudden) and tried to install Vista on this one as a way of forcing it to show, only to get an error code 0x8007000cl. I then split the new 1.5 tb drive into 98 gb and about 1300 gb via the vista DVD's drive list that comes up, partitioned the 98 gb, and now that smaller one at least shows up under 'Computer' but it still wont allow me to format it.

Any ideas please? Thanks.

The fact that your system will not load your disk is worrisome, but I suspect you have a defective drive, or inadequate resources. Tell us more about your computer brand and model, or about the motherboard.

I own a Satellite A100-1AI and have moved from Vista to Wndows XP?

My DVD drive has been discovered as a HL-DT-ST DVDRAM GSA-T20N but is only showing as a CD drive in the My Computer screen.

Also Device Manager is showing Mass Storage Controller and SM Bus Controller as an unknown (other) device.

Since moving from Vista to XP I have not adjusted my BIOS settings

How do I clear these unknown devices and make my DVD drive see CD's

Many Thanks in advance


Answer:Satellite A100-1AI shows CD drive but Device Manager shows DVD drive

Just one question;
Can you read and burn CDs?

Regarding the unknown devices:
These devices are supported only by Vista and therefore there are no drivers for Mass Storage Controller.

Check this:

+After installing Windows XP there could be a yellow exclamation mark by a "PCI Memory Controller" or *Mass Storage Controller* in the device manager.+

+This device is likely the Turbo Memory former Robson module.+
+This hardware will only supported by Windows Vista.+
+Therefore there is no Windows XP driver.+

Answer:Cannot save to my hard drive. It shows my disk spa...

Hi royang67 Firstly check to see if there are any unwanted programs installed. If so, uninstall them. It will be worth running Disk Cleanup on your drive - type in the search box from your start menu/screen Disk Cleanup right click & choose Run as Administrator. Select OK on your C: drive. Once it has finished calculating make sure all boxes are checked, click OK, then Delete Files. System Restore can take up lots of space, so go back to Disk Cleanup now select the "More Options" tab. On the "System Restore & Shadow Copies" part, select "Clean Up" / Next, follow this guide, to do a Disk Check. If you're STILL showing as Disk Full, then it may point to a failing hard disk, and it will need replacing. You have made backups of everything, yes?

Hello Everyone,

Over the last couple days, I built a new PC and installed windows 8.1. Initially I had some issues installing windows, so I unplugged all my drives except the SSD and DVD. I installed windows to my SSD.

Everything works great!

Now I started adding my drives back in 1 at a time. When I plugged my 2nd SSD in, it showed up in BIOS, but not in Disk Management or Device Manager. So I booted back into the install CD, it showed up in the disk manager there. Since this was also a blank SSD, I partitioned and formated the drive from the install CD, then exited the installer and booted back to my windows drive.

I have 2 SSD drives working great!

Now to add my 2TB HDD... Same issue, it shows up in BIOS and the install disc, but not in Disk Management or Device Manager. This drive does not have a boot partition on it, however, it does have two existing data partitions. They were made from my previous windows 7 system and the option to delete these partitions is grayed out in the install disc menu. I also have some data that I would like to keep on it. I have a USB dock that I can use to read the contents of the disk just fine. Everything is there and in working order.

Can anyone help me out here? What is different about Windows 8.1 that is preventing my hard drives from showing up in windows proper? I am reading things about UEFI online, but nothing seems to fit my exact scenario. I will try and post some screen shots when I get back at it.

Ok I installed Windows on an old 80 gig HD I had laying around, and everything was successful. The system was working great until recently when I try to boot up the machine I would get DISK BOOT ERROR please insert bootable disk. I would then restart the machine, and then it would boot into Windows fine. I found it very odd, but thought it was because the MBR may be confused since on another HD there used to be a windows installation and I had to remove it manually. (Not sure if that was the case)

Ok, so today I tried to fix the error cause Windows would refuse to boot. I ran Windows setup to check the partitions, and initially it showed that my 80 gig HD was unpartitioned space. I reset the machine, went into Windows setup again and then it showed the partitions.

At the current moment I can't get my machine to detect the partitions for the life of me. I currently have it removed from the computer, plugged it into an external HD case and plugged into my laptop. I ran Norton Partition Magic and it's detecting the HD as unallocated space.

Is there a good program I can use to recover my lost partition table? Is it a lost cause? What the heck is going on?!

Please feel free to ask questions, and I will respond promptly. Thank you for reading.

Hi everyone. I'm on a Lenovo 3000 n100 laptop with Vista. Lately I began noticing that the free disk space on my hard drive was filling up, so I deleted most of my movies and games. Now explorer shows me that I have 46GB of space free within my 106GB hard drive, and that I've used 60GB.

However, I am quite positive that I have NOT used 60GB of disk space. Highlighting all of the files in my C drive and hitting "properties" shows that they take up 25GB. I downloaded a program called JDiskReport which shows my disk usage and, as I suspected, only about 30 gigs of disk space is reported in C.

Now, I've run chkdsk and done a system defrag. I've gone into the windows disk cleaner utility and deleted most of the temporary files, including the hibernation files. I cleared all but my most recent system restore point and I also checked my shadowcopy usage in the command line (it says shadowcopy is using only about 1 gig). I ran ccleaner and have done full scans with windows defender and AVG.

Anyway, I'm all out of ideas now and I want to reclaim my 30+ GB of hard drive space! . The 60GB I'm supposedly using was actually around 75GB before I went through all of the above steps, but it still tells me I'm using twice as much disk space as I actually am. I've uploaded a picture below. Any ideas would be greatly appreciated. Thanks!!

I have emailed Paragon and am awaiting there reply, but you guys seem to know a lot more and try and solve the problem

Up to this point I have used either Acronis or Paragon for my backups, I prefer Paragon over Acronis, mainly because the restore by Paragon is far quicker.

I have both bootable CD's, but in this instance I would like to concentrate on Paragon.

I downloaded Paragon's Advanced Recovery CD. 2009 Build 6730. Put it in my rom and booted ....... looked at a black screen for 10 minutes. Removed it and rebooted, it got stuck at the loading of Vista, then I got another black screen no hard drive movement.

Rebooted again, this time with the regular Paragon bootable CD. It booted into the recovery console.

Now this is where things go from bad to worse. I tried finding my OS, after a lengthy period I received an error disk 2 i/o fault!!! ....... no operating system found.

Now disk 2 is my external hard drive where my backups are kept.

So I rebooted with the CD in, went into the recovery console and clicked on "safe restore", after playing the waiting game I get a message disk 2 i/o fault!!!.

Took out the Paragon CD, put in the Vista one, tried a repair, but there was no OS to repair .

So I installed Vista, and because I didn't want to have to reinstall all of my programs again (yer lazy I know, but that's what backup's are for).

Alright, I have a whole bunch of my music and videos on my external hard drive and I got a new Dell XPS 8300 yesterday. I had been using my external hard drive just fine for the past 1-2 yeas now with 2 different laptops, working fine. I plugged it yesterday to transfer all my music to my new computer and it seemed to be working fine. There was an error as the copy rate slowwed so I decided to delete and try again. I did that about 3 times and then decided to just copy the music album by album. Eventually, I don't know how it ended up happening, instead of the Hard Drive coming up as Seagate on the My Computer Tab, it started showing up as Local Disk: J on my Dell and Local Disk E on my laptop now.

Hi, first I would run the Seagate diagnostics to check the hard drive is still healthy following this guide.

Identify the make of your hard drive and then use one of the links below to get the manufacturers diagnostic for ISO CD. Burn the image file to a CD, boot the PC with the disc in the drive and run the diagnostics. You first need to set the CD drive to 1st in the boot order in the Bios setup.

If you do not have an image burner use this free software to make the CD.

Getting ready to retire my desktop, and am working on moving YEARS of data to a new home server. In the process, I wanted to verify some info on my hard drives. (2) 500Gb WD SATA drives. First drive partitioned into (2) virtual drives (C/D); second drive partitioned to (4) drives (E/F/J/unmapped). C is the only bootable, only Win XP SP3 (fully updated) for OS.

With the additional drives from USB sticks, USB drives, and memory card slots, I use Disk Manager a lot to remap drive assignments. Until now, I have never had any issues.

I went to start combining data onto a single drive, and get ready to physically move the single drive into the new server. Howeveer, when I went into Disk Manager, the first hard drive is not shown - the listing starts with HDD 1 (E/F/J/unmapped). Disk 0 (C/D) is nowhere to be found.It is also not visible in Device Manager.

However, it is obviously working (I boot to it!), I can find it in WinExplorer, and Defrag sees it.

I have been scouring the internet, and only found a few (current) cases of similar things, but none of their suggestions have worked. I have run several security scans, rootkit detectors, spyware scans, etc, to no avail.

Any thoughts would be GREATLY appreciated.

What OS? I cannot find anything about your adapter. Are you talking about an ultrabay device? USB housing? If it's an ultrabay device, it delends on which FRU it is supposedly compatible with. A T400/T500 ultrabay adapter will not work on a later machine, but an adapter intended for a later machine will work in a T400/T500.

My PC no longer recognizes my external HDD. I unplugged the power, plugged it back in. Same with the USB cable. Rebooted. Then my computer wouldn't reboot and windows did its automatic self repair. Nothing.

I unplugged EVERYTHING and left it that way for about 30 minutes. I plugged EVERYTHING back to my computer and turned it on.

Windows booted up fine. I plugged in the external HDD and windows had that little icon telling me it was installing drivers. I was excited to think that it finally would recognize my external HDD.

Of course, it didn't work. The HDD does not show up in my computer. It does show up in Device Manager and Disk Management.

Device MangerUnder Disk Drives it lists it only as "WD"
My other drives it has a nice long name like "WD 7500AAK External USB Device"
Under properties it tells me Volume information for the disk cannot be found. (The very first time I did that prior to the reboot it said there was 0MB of space on it).
It claims the device is working properly

HiMY T42 died and I have ordered a T500 with a 64 GB SSD, and got this adapter as well.The Adapter has come, the T500 has not.I extracted the 100 GB SATA disk -- Seagate 7200.1 from my T42 and would like to use it as a backup or extra disk in the T500 using this adpater.However, the adaptor has a relatively short connector whereas the Seagate has a set of pins that run almost the full width of the drive -- they dont seem to be compatible at all.Surprising.Any thoughts asto how to solve this problem?Thx in advance

Answer:T500 Serial Hard Drive Bay Adapter II -- how to install Seagate disk in it

ulall, welcome to the forum, the adapter you received is only suitable for S-ATA hard drives, your T42 has an P-ATA hard drive and is unfortunately not compatible with the adapter. If you wish to use the drive from the T42 you will need to obtain an external USB caddy. An other alternative would be to obtain an S-ATA drive to use in the adapter you have.  Hope this helps  edit; typo Message Edited by andyP on 11-23-2008 08:23 PM

hi computerfriends,

I got a problem, my external hard drive (westen digital 1.0TB) isn't popping up my computer. I can see it in devices (USB to ATA/ATAPI bridge) but i can't acces it. What i've done already:Computer Management-> Disk Management. Than ive to initialize the disk, i can choose between MBR and GPT. In both cases i got the error: Data error (cyclic redundancy check). I can't chance any letter
Downloaded different programs but non of them worked

I've to get my files, it's important. I hope some of you know now the sollution.

Answer:External hard drive shows up in devices but not in my computer

Hello indoow and welcome to Seven Forums. Couple of things to try:

1. Try using a different USB port.

2. Try changing the drive letter.

3. If you have access to a live Linux CD like Ubuntu you may find that Ubuntu will recognize the external hard drive in Computer.

4. The hard drive may be going bad. You could go to the manufacturer's web site and look for diagnostic tools to check the drive. Or you could use SeaTools for Windows from Seagate (works on non-Seagate drives as well.)

Well, i'm getting riiiigggghhhhh at the end of my tether here

I'm running a Toshiba Laptop 2.8ghz
512 mb of ram
BIOS: Toshiba version 1.8 (updated)
Windows XP professional SP2

Right, so i purchased a Western Digital 200gb hard drive and mounted it onto an external case with USB 2.0. This external case has a 12+ volt adapter with 1.5am (max 18W) . The hard drive is set on Master.

(note: i have anoter USB 2.0 80gb seagate drive that works like a charm, connected to same computer)

Here is the problem, i connect up the 200gb HD to one of my ports. THe computer happily runs that new USB mass storage device says hello. Then everything goes to hell. I opened up explorer expecting my lovely new HD to appear. Uh oh, this is goign to be one of those long days (week really).

I opened up disk management expecting to find it there and only needing a new drive letter assigned, but nope the new HD is not there, just the two i already have (internal, and external 80gb). Its as if my computer refuses to acknowledge it

Next i go to device manager and lo and behold there is a new entry under disk drives that says "Disk Drive" So here i'm thinking what the heck is going on?

I contact Western Digital demanding nicely for an explanation. We go through all the usual basics and crap ie viruses, spyware and drivers.

Answer:200gb hard drive visible in Device manager, not disk management.

-model: 6L300R0
-300GB PATA133 HDD

Ok, so the problem is it used to have my entire schoolwork, business, music files, and so forth on it. It worked great and as soon as I got all of my information transfered onto it, it went kaput. Ever since then I've been unable to view any data on it. The way it works is it connects via USB and lights up, the icon usually (not always, but usually) appears in my computer. I can open it, but there is nothing there, it is just an empty window. So, even though all my data is there, I say whatever, I need the storage space, so I'll just reformat it. well, it allows me to right click and select reformat, but nothing ever loads or happens.

Hi all,
I am attempting to install Win7 in an Inspiron 1545 with a new SATA hard drive that was purchased. When i insert the drive, I get "Internal Hard Disk Drive Not Found." I have verified the drive is not showing in the BIOS, I've already attempted to reseat the drive several times. In addition, I've attempted to load the chipset drivers, SATA drivers, etc from Dells website, the drive still does not show in the OS install when booting to DVD or in bios.
I dont believe it to be an issue with the new drive, as I plugged the new drive into another model Dell laptop and it recognizes the drive fine in BIOS, also I can still boot to the previous hard drive in this laptop without issue when i plug it back in.
Is there a specific driver, etc that I need to use for the drive to be recognized or other thoughts people have?

Answer:Inspiron 1545- replacing hard drive, new SATA drive not found "Internal Hard Disk Drive Not Found

This is strange - either the new hard drive has a rare compatibility issue with your onboard controller (I use a 500Gbyte in my 1545 without probs)) or it is a mechanical problem.I would take a close look at the physical dimensions and compare your original hdd with the new one.Watch the video (even though it's about a 1525 (similar to an 1545) and an SSD hdd) -  go to 2:20

With my 2009 Seagate 500 GB sata hard drive, the re-allocated sectors count shows 2 bad sectors, in the Ubuntu 10.04 disk utility for the smart data. In this multi-boot desktop PC the XP with a drive monitor program called, Active Smart shows this drive health status as good, including that reallocated sectors count item, so is this not to worry about for now, or what. I do monitor the hard drive temperature, which does stay cool enough, in the seventies up to about 80* F.
Or can this be caused by mixed partitioning methods, since the new way is now align to MiB, and not align to cylinder as it was. I used the GParted tool to create and change partitions when it was set as default to align to cylinder, but then I recently used both my Vista Disk Manager, and the newer version of GParted to re-size some of the partitions, which both now use that align to MiB method by default, which often has near 1 MB gaps between partitions then.

I have a backup drive that we had used for for a while (WD 6000aak), previously in an external drive enclosure. I connected it today via USB to find that the computer has the driver installed, the drive appears in the Devices list, but it does not show in My Computer. In "Disk Management" the drive appears but is not assigned a drive letter. Also, all the options for the volumes are greyed out and cannot be selected - thus I cannot assign a drive letter.

I have tried this on multiple computers. I have also removed it from the enclosure and connected the drive via SATA... the result is identical. I checked the bios and the drive appears there.

The drive does spin when powering up. It is hot (even though it cannot really be accessed).

Any suggestions? Is this drive done?

Answer:Hard drive installed, shows in Drive Mngmnt, in Bios, but not in Comp.

Go to Disk Management, in the bottom part of the screen, right click the drive, select 'change drive letter or path', next window select add, next window select a drive letter from the drop down box. For an external drive it's best to use a letter lower in the alphabet. If disk management wants to initialize and format it, don't do it if there is data on it you don't want to lose. If no data or if you don't care, go ahead. It will show in computer when a drive letter is assigned.

Answer:External Hard Drive shows no files/my computer show approx. 600 GB occupied

Welcome to Major Geeks!

Sorry to hear about your problem. If you do not have backups of these files and have already tried several restore programs, it may be time to turn the drive over to a person or company that specialize in data recovery. (Please don't be offended by this. I've been working on PCs for over 15 years and there are many times I've had to consult a specialist as well).

Please be aware this could get quite expensive. If the drive can be recovered intact, you're likely looking at a few hundred dollars including the cost of a new drive. If the drive has to be sent for disassembly in a "clean room" to read directly off the platters, it could go as high as $1500, depending on the amount of data recovered.

Do not allow any recovery program you use personally to reformat the drive or remove/resize partitions - this could go further damage to the files.

Sorry for the bad news, but I hope this helps.

My computer failed to boot a few weeks ago. I took out the C drive and put it in an external drive case on my other computer in order to retrieve outlook emails, bookmarks, etc. The drive is 250 gigs. It only shows an 'N' drive, 130 gigs worth of data, which must have been a partition. The C drive isn't there. Is it corrupted? Will be I be able to retrieve anything from the C drive?  If the drive is corrupted, why does one partition show up and not the other?

Answer:Hard drive doesn't show C drive, but shows the other partition

I had a similar situation. I was able to get data off the drive using a Ubuntu live cd. Burn the iso to cd, put the drive back in the computer and boot to the cd. If you can see the drive in Places then you should be able to get your data off. Please note the "if" and "should".Good luck.

I've connected an external USB drive, but when I go to My Computer it shows it as a network drive. In addition, it gives it the same name as the mapped network drive that already exists there. When I change the name of the external drive there, it then changes the name of the mapped network drive, so again they both have the same name, although the drive letters are different. Any ideas how to make the external drive appear where it belongs in My Computer, under Hard Disk drives?

I'm also seeing some other odd behavior on this computer, and since it may be related I'll mention it. When I first opened my Computer, it showed the same networked drive repeatedly, with every letter from F thru Z. I deleted them all except one, but now every time I reboot, I get a logon connect dialog that asks to reconnect one of them. So with each reboot it is adding back one of the duplicate mapped networked drives that I had deleted. I expect it will eventually end up with all the alphabet letters like it was when I first sat down at this computer.

My main concern is to get the external hard drive to appear where it belongs.

Hello everyone, my working laptop is a T 400 running on Win XP. I would like to run a Windows 7 installation on a physical hard drive which won't be possible with my employer in the near future.My idea is now to have a second HD in the Serial Hard Drive Bay Adapter III (let's say theThinkPad 320GB 7200 rpm Serial ATA Hard Drive) on which I would install Win 7. I would then configure the bay adapter to be the primary HD to boot from. I would reconfigure the system to use the internal HD everytime I need Win XP together with my other company stuff.I don't want to install Win 7 just in another partition as I don't want to risk anything happening to the XP machine ;-) Is the above described scenario valid or do I have to take anything else into consideration? Thanks in advance!Sascha

I am not sure whether I should be posting this in the Windows forum or the PC Hardware because it involves both.

I have an external 320 GB Transcend Drive with a lot of important data.
Recently, I unplugged it from my PC and took to another to get some files.
One the other machine (Vista), it didn't show up as far as I can remember, thought that was strange so i brought it back to my Laptop (Win 7, Dual Boot with Ubuntu 10) and it only showed as Local Disk, I have tried to find useful information on the net but some is very vague and some is outright stupid and irrelevant.

The fact is that the HDD is not broken. When in Ubuntu I can view the contents fine and everything is there, no freeze ups or anything, but in windows the drive shows up as Local Disk, I don't think it is a drive letter conflict.

The Device shows up fine in the Device Manager.
I'm sure some of you have solved this problem as it seems many on the Internet have.
If so please tell me in a few steps how you resolved it.. I am not formatting as I do not deem this necessary since I can access my data fine in Ubuntu.

Kind Regards

I purchased the Thinkpad Serial ATA Hard Drive Bay Adapter II P/N 43R1980 as one step to have a Raid configuration for my W500 with Windows XP.  My question is, will any serial ATA hard drive fit the adapter? Lest you think the answer is obviously yes, my former computer was a Toshiba Portege. Toshiba's hard bay adapter required a special fitting for the hard drive, presumability so one would have to buy the hard drive from Toshiba rather than a third-party vendor. Clever - a ten-cent part increased the cost of the hard drive by several hundred dollars. From the Thinkpad manual the adapter appears to have a standard fitting, but I would like conformation. Many thanks for an information. Rick

I have been looking for the p/n for this skinny adaptor shims/rails, but have been unsuccessful. So I have just taken two rubber bands one for each side to limit the vertical fit and it did the same for the lateral. The drive is pretty snug in the adaptor.One of this forum's moderators, AndyP, has been very helpful on this issue.

please is there a genius out there that can help me!!!!!!!!!!!

Answer:Hard drive not recogized in my computer or disk management

Timemachine shouldn't automatically synchronise to the hard drive, unless told to do so. Also, in order for time machine to function on that drive, it requires it to be formatted in the MacOSX native filesystem.

In case your not aware, Timemachine is Apple's backup software, designed to backup Apple systems.

If the data on the hard disk is not of any consequence (e.g. it contains no essential data), it can be formatted as NTFS, which will then be read by Windows. Unless it has been formatted as a Mac OSX partition it should be read natively anyway. In other words, it should be NTFS still.

Lets go back to basics:

1. If it's an internal hard drive, does BIOS identify the hard disk?
2. Your positive disk management doesn't identify the hard disk?

You could use a bootable partition editor like GpartED to boot from the DVD drive and inspect all your connected partitions.

You could also boot from a Linux Live distribution like Ubuntu as well, which would enable you to check your connected partitions/drives.

The fact Windows is refusing to identify that hard disk is leading me to suspect its been re-formatted as a Mac OSX filesystem and as such can't be read from Windows. If its been re-formatted your data is already lost, in which case just formatting it will resolve your problem.

I think your HDD is corrupted. Can you run a Linux (Ubuntu) Boot-CD, and can it see anything on the drive? If so, I would back up everything you can. Your HDD may be dying.

i bought a 250gb samsung external hard drive ,when i connected it to the usb port my computer could not detect it either in disk management and my computer ,so i decided to rebot the computer and go to the bios ,i could not also see it in the bios.funny enough my friends computer could easly be seen when connected both in the disk management and my computer

please help me .am currently running windows 7 build 7077

Answer:External hard drive not seen in disk management and computer

USB drives dont show in BIOS.

The USB adaptor may be USB 2 and your USB may be usb1 and as such is having trouble seeing the drive.

Or your USB sockets or drivers are faulty, try another USB device in them

I believe this question best fits here rather than in the security section, so here it goes.

I have a Dell Inspiron 9300 laptop which was running Windows XP, service pack 3.

Two days ago, my laptop began running extremely slowly, which I believe to be the side effect of a virus (The slow running happened immediately after I approved a program - I don't know which one- for outbound internet access).

Also, I had not installed any software or hardware recently.

I had resolved to install some anti-virus software to correct the problem, as the software I had was out of date, but I found that my computer was running so slowly that I could not install or run programs anymore. I decided I would reformat the disk.

I restarted the computer one last time to see if I could get a few word documents off that I want to retain, and was given a blue screen which reads "UNMOUNTABLE_BOOT_VOLUME", then at the bottom of the screen reads "Technical Information:

I have tried starting windows on subsequent attempts using the following options:
-Safe Mode
-SafeMode with Networking
-Safe Mode with Command Prompt
-Last Known Good Configuration

Each time getting the same "UNMOUNTABLE_BOOT_VOLUME" error.

I figured I should try and boot the computer off a bootable CD, i.e. my Windows XP disk, however when I change the boot sequence and try to boot off the CD I get the err... Read more

OS: Windows XP SP2

well... my computer is on for many hours... non-stop
the HDD i am having problems with is an 80gb BARACUDA SATA HD
It's full of TV shows/cartoons and useless stuff... so thats the reason why i labelled it "TV Shows".

the issue i am facing is:
I start my computer, & whether or not i access the TV Shows HDD, it just disappears from the explorer / my computer drive list after any arbitrary time period.
I then restart my PC and there it is again. But then again disappears after a long time.
When i go to device manager, the hard disk is not to be found even after scanning for "new hardware". It's like the HDD switches off.

My computer is permanently on and the "TV Shows" HDD is seldom used.
No background disk usage occurs on it either.
I have other SATA HDD's too but none behave in the similar manner.
The computer heats up so i have kept the side case open too.

After using "Disk Investigator", it reports no problems with any of the HDD's.
Although the temperature readings of the HDD are:
HDD 1: 35C
HDD 2: 43C
HDD 3: 42C - - "TV Shows"... the one giving problems
which is fine, although they are too hot but it's because the room temperature here is between 20C - 30C.

What could be wrong?
I made sure the cables are fixed properly, changed the SATA data cable, also switched it from SATA port 2 on motherboard to SATA port 3, but only this HDD plays hide n' seek.

I have a Western Digital (WD) 250gb external hard drive and run Windows XP on my Asus Eeepc laptop.

One day I pulled my external hard drive straight out of my computer (didn't use "safely remove hardware"). From now on it isnt displayed in my computer, and it doesnt appear in disk management either. When I open device manager and then open my WD SES Device, it tells me the device is working properly. I have tried updating the driver and uninstalling it, but everytime I plug it in reinstalls itself and tells me it is working fine.

I am not a computer guy. I have read other forums and none have a solution for me. Does anybody know how to access my external hard drive? (please write responses in simple language with simple steps I can follow)

Hello all. I've used this forums many times before and decided to join. The information is very good here.

Anyway, I'm working on a friends computer (Dell Optiplex GX520 with Windows XP SP3) who had some spyware on it. I think I have it all removed but I have this one strange issue I've not come across before. I discovered it when trying to run the disk defragmenter and I kept getting an error message that said it was unable to start. The C drive is present there and other USB drives that I connect as well. But when I go into disk management, the only thing listed are the USB drives and the CDROM drive, NO C drive or any other volumes. Also, when I tried to run chkdsk on reboot, I get a message saying that it could not check the disk for some reason (flashes by too quickly). Can someone shed some light on possible conditions that would cause Disk Management to not be able to see the main Volume?

BTW. I removed some trogans and installed MS Security Essentials. Computer seems to be working fine except this issue. I don't have much history on the computer. Hard drive is reported in Device assignments as ST3808110AS, I'm currently running sfc /scannow to check Windows files.

System File Check just finished. I need an XP Pro disk to repair Windows and I don't have one. Oh well. Please let me know if there's a way around this.

Answer:No hard drives detected in Disk Management but C drive is in My Computer. ?

Can you post a screenshot from Disk Managment?

Logically...any connected drive should always appear in two places...the BIOS and Disk Management.

The only possible reason that I can think where this might not if two drives are assigned the same letter by Windows, only one can be reflected.

As for C: being reflected in Windows/My Compter...any version booted into appears as the C: drive, as any person who does multiboots will tell you. The C: drive is nothing but a designation for the O/S partition/drive booted into.

As for your XP Pro situation...there is no way around the requirement for the system files for the applicable O/S installed. XP Home is not Pro and vice versa.

I've been having this problem for a few months now. I recently built my own computer, having been on a lap top for a couple of years, and found my old external hard drive. I plugged it in to the new computer, and it said something about needing to be formatted, which I promptly did due to nothing of importance being on it. I went to sleep, and woke up to see that it couldn't be formatted.

This is where my issue begins. It no longer appears in Computer, or Disk Management. Disk Management won't even load if I have the drive plugged in. There seems to be no way at all to format the drive, since Computer, and Disk Management both don't load when the drive is plugged in. Any help?

Hi, I recently purchased a Seagate Barracuda 7200.7 for my system, and I tried connecting it as a slave to my 40 gig WD.

I have them set up properly, jumpers in place. In bios, and boot-up they register properly. However, when i get into XP, I can't see the new HD's icon in my computer. It shows up in device manager tho.


Answer:Hard Drive shows up as CD Drive XP

I too had bought a Seagate with the same problem you're having. The solution is they should have sent you a disk with a program called Disk Wizzard 2003 or 2004, now. If you run through this program you will find a section to format the new disk so your system can see it. After I ran this I found it in My Computer then for the heck of it formated it again by right clicking on it and selecting format. Then I formated it NTFS. Now everything is visible.

It still works fine on my laptop, and when I plug it in to my tower, it still recognizes that "External USB 3.0" has been plugged in and downloads the drivers. However, the drive appears neither under my computer nor disk management, nor diskpart -> list volume.

I have a Samsung s2 1tb external hard drive.

Today when I hooked it up to my laptop it would not load. It will shows local F drive when it usually will say samsung Drive.

A pop up box will then appear stating "you need to format drive"

I know if I reformat it I will lose all my data which I will not do.

When I look in device manager it states that the external hard drive is installed.

I attempted to go through start menu and type cmd then F: and it states "The volume does not recognize this system file. Please make sure all required system drivers are loaded and the volume is not corrupted."


Answer:Samsung s2 external hard drive not loading showing local disk F drive

With the external drive connected, Go to Disk Management (Start > type: "computer" > click on Computer Management > click on Disk Management)

Determine which disk is the external drive.
If the external drive shows here as a healthy volume, Right click on the large box to the right of the "Disk 1" / "Disk 2" lable and choose: Change Drive Letter and Path.

If there is nothing but a grey box or "Unallocated Space" next to the disk number then Right click on the disk number (the box) and choose: Change Drive Letter and Path.

Change the drive letter to anything else > OK.

If you can't do any of the above post back. If you can post a screen shot of the Disk Management window that can help.
Do not initialize the disk or format it or you will lose your data.

Much appreciation for info to help me do this, confused and sad.

Answer:Inspiron 14z-4423 Hard Disk Drive not found: How to Reseat Drive?

The 0142 error is a HDD failure. This is a smart error and indicates that the HDD is failing or already failed error - see this article for reference -
So, reseating the HDD will not positively help in this case. If you would like to reseat the HDD anyway and check - download the service manual here -
Also, the 0332 is a video card related error. So, the motherboard needs to be replaced.
Personally, I would suggest you to invest your money on a new machine than to repair this system. However, that is your discretion.
Also, please click my DELL-username and write me a private conversation with the service tag and your Name for case records.
Let us know if you have any other queries.

Well after a few tries i somehow got it to recognize the hard drive upon startup and it tried to format it i think, although as soon as i saw that screen i powered down and now the hard drive is no longer recognized by either computer, even in the bios it says the total memory is 512 mb with it connected to hard drive spot of the original dell. I would really like to get my dell working again but it gives me the error Invalid Boot diskette Insert Boot diskette in A: I do not care for restoring the files on the hard drive they are worthless to me i just want to get my computer working again any help would be greatly appreciated, Thank you.

Place OEM Windows CD into the CD or DVD drive and boot off of this disk. If your system doesnt want to boot off the CD or DVD drive go into bios and set the CD or DVD drive as 1rst boot device in boot order. Once you successfully boot off of your optical drive you then can delete the partition on the hard drive, create new partition and reformat, then install clean installation to that hard drive. If you dont have recovery or oem cd available, you will have to buy one.

Hi. My external hard-drive stopped working yesterday. This is what's happening:

I plug it in as usual, then it says "You need to format the disk in drive F: before you can use it. Do you want to format it?".
I'm thinking it's more than likely an issue of having pulled out the usb cable without clicking 'safely remove'.

Yesterday I actually got it working again briefly by typing "chkdsk F: /R" into command prompt. Now when I do that it doesn't work, it says "The type of the file system is NTFS. Unable to determine volume version and state. CHKDSK aborted." And when I double click on F: drive in my computer it says "F:\ is not accessible. The file or directory is corrupted or unreadable".

Are there any other options besides using some sort of data recovery tool (I'd rather not do this just because it takes a long time)?
