[Seriously need help] External hard disk causes hard drive failures & OS crashes

Question: [Seriously need help] External hard disk causes hard drive failures & OS crashes

[Seriously need help] External hard disk causes hard drive failures & OS crashes
The thread is rather long. Only read what you think important. Skip the rest!

We have a serious but mysterious problem. We have spent already one week but drawing a blank.
Two hard drives have been crashed and failed (unreadable). One computer has hung a few times unexpectedly and had one weird restart (no memory dump produced).
I suspect all the recent problems have to do with the new USB external hard disk (Buffalo MiniStation Lite: HD-PE250U2).

Formatting USB external hard disk
Originally I would like to use the program given by Buffalo to format the external drive once but we failed. We simply used Windows to reformat the drive into NTFS. I did not use the TurboSpeed advertised by Buffalo, or run its free program.

Case A: Multi-transfer causes system crashes?
The first time we met the problem.
We were trying to help a friend to backup data on an old drive, about a few years old. We plugged in the Buffalo USB portable hard drive and transferred a whole lot of files to the drive. Several cop/cut-and-paste operations were active at that time. The whole system completely froze up. It doesn't respond at all. Only a hard restart could help.
Restarted. Tranferred again. Several cop/cut-and-paste operations were active.
Hard drive crashed - the beginning of the nightmare!
Windows restarted. Chkdsk was running. Saw many lines of messages with:
"File segment record XXXXX is unreadable"
"File segment record XXXXX is unreadable"
"File segment record XXXXX is unreadable"

Chkdsk run very long time (perhaps a hour or so), complaining that some couldn't be fixed, some okay.
Initially I thought it was simply because it so happened that the hard drive failed in the middle of transfer. But the same nightmare occurred when we tried to plug it into another computer.

Case B: Open folder causes system crashes?
I plugged in the Buffalo USB external hard disk on a laptop computer.
I tried to check if transferred files were safe. I have no ideas how to check but it looked okay.
Some files were transferred to and from the external hard drive. I made sure only 1 copy-paste operation was active this time.
Then computer hung for a while and displayed Blue Screen of Death. (I recorded the message on a piece of paper but it was lost later).

Restarted. I believed chkdsk was automatically run and fixed some errors found (not too sure about this). I resumed the work. I made sure only 1 copy-paste operation was active this time.
The system hung this time when I double clicked on a folder (to see what contents inside). Another Blue Screen of Death popped up later:
0x00000077 (0xC000000E, 0xC000000E, 0x0000000, 0x009C7000)
Info on this BSOF:;en-us;Q315266

Computer restarted. Chkdsk was automatically run. Nightmare again!
"File segment record XXXXX is unreadable"
"File segment record XXXXX is unreadable"
"File segment record XXXXX is unreadable"

Chkdsk attempted to fix the problem but it complained "not sufficient space". Then I received STOP: C000021a Unknown Hard Error

Oh my gosh! What's up? I don't believe it so happened AGAIN the hard drive failed when some actions were performed between the hard drive and the USB external hard disk. I started to feel something went very wrong. Is it virus?
Case C: Scanning for virus causes system crashes?
Searching on the net didn't find any case which was similar to mine.
I tried again on a new computer. Fresh Windows copy. New hard drive (less than 1 year old). Only a handful of programs were installed.
I downloaded Avira and did on-demand scan for my internal hard drive first. No virus was found. Was I safe now?
I plugged in the USB external hard drive and scanned this drive for virus.
My new computer froze when the scanning was close to completion (I believed the progress was about 90%)

Computer restarted. No chkdsk was run automatically. I scanned again from scratch.
I paused it after a while. I had a weird thought that the USB external hard drive may crash our system when it's overloaded.

Then I was browsing on the Internet (perhaps a few hours or so). The scan was kept "paused". The USB hard disk was still plugged. My computer hung again when I tried to click to view a video on YouTube.

Case D: System crashes without USB hard disk
OK! I switched the computer off completely and unplugged that "devil".
Using the computer for about one day, computer hung again at night.
Hmm... This computer is new. What's really wrong if it isn't related to the USB hard disk?

Case E: Transfer a large file causes system crashes
This test attempts to transfer a single large file (4.33GB) from USB external hard disk to my computer
First attempt: System restarted mysteriously in the middle of transfer. I set it to display BSOD when crashes. The computer shouldn't restart. I didn't see any memory dump either.
Second attempt: System hung after the transfer.

I'm desperate! It's just so strange! I have absolutely no ideas why something like this would happen.

My questions:
Really what's going wrong? I don't think USB external hard disk is such a so unreliable product. There must be something I'm missing...

What checking tools (free or paid) do you recommend to verify whether the transfer is faultless, files being safely moved/copied?

What file recovery tools (free or shareware) could I use to recover (at least most of) lost data in the hard drives? The tools have to be well (professionally) written. I tried a few but all failed to recover all except a small portion of data. Professional recover services are out of consideration because I know it's very expensive and the data isn't utmost important.

How could I save/recover data from the laptop computer? I tried to go to safe mode but failed. I received STOP: C000021a Unknown Hard Error. Chkdsk once complained "insufficient disk space" when attempting to fix "file segment unreadable" error. Is it the cause? I also inserted SeaTools CD to do a scan. It said it's loading something to the RAM drive (I had only 1 internal hard disk on the laptop computer). It's loading but never finish. I couldn't even enter into the main screen of SeaTools. I could only see a black screen.
Tell me anything else you want to know.
Ask me any piece of information which helps to troubleshoot the very root of this series of problems.

Answer:How to fully use the extra hard disk space for external hard drive?

It should have about 465GB, what are you seeing?

You will not have 500GB due to the conversion between binary and decimal for reporting sizes.

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).

I connected it today and in my computer it shows up as Local Disk (G:), when I click onto it to try and access it file explorer crashes and only sorts itself out when the drive is unplugged.
I tried uninstalling the driving and had no luck with it, can't access anything that involves the hard drive to format it either

Is there anything else I can try?

Answer:External Hard-drive crashes when i try to access it

Hello and welcome to the Tenforums!

Interesting problem. I, too, have the same external drive but when plugged into my USB3 port it shows up as TOSHIBA EXT (E: ).

This suggests to me that your registry has got corrupted in some way because it should not be showing up as a Local Disk. Can you check how it appears in Disk Management (right click on the start button to access this)?

To restore your registry the simplest way would be to restore your system to a restore point before this happened, but that all depends upon whether you set up W10 to create restore points or not. Hopefully you did.

Answer:external hard drive crashes laptop

Firstly I would connect the external to a desktop computer to see if it works well there. If it does, I would copy all the critical files to removable media.

Also if you have access to another Exteranl drive try it on your computer to either rule out the computer as the problem or the external drive. It could also be as simple as a bad USB Cable.

I got errors from Google that my computer had a virus but nothing I ran could find a virus, then the machine would not boot. It would get to point about the time windows tried to load and hit a blue screen. When it rebooted it would ask if I wanted to boot normal or safe mode and then start the whole fail blue screen over. I tried taking the drive out and connecting to my other machines as an external hard drive. When the drive connects to my other machines it brings the other machines down hard - blue screen exactly as if I had tried to boot on the original machine.

The goal is to get the files off the bad drive. I was just shocked that connecting it to my laptop or my other desktop took those machines down just like I was trying to boot the bad drive from the original machine. I am open to suggestions on recovery of any kind.

The original machine is a Dell XPS 8300 Intel Core i5-2320 processor Windows 7 64 bit
The drive is a Seagate 1 Tb 7200.12
The machines I tried to connect faulty drive to as external hard drive were both Win 7 64.
The external hard drive bay is Sabrent USB 3.0 to SATA External Hard Drive

Thank you

Answer:Hard Drive Crash - Trying to connect as external drive crashes all

There may be a couple of vectors to the virus. One for the boot sequence, another as an autorun in its root folder. I would try usb tethering the drive to a machine on which autorun or autoplay is completely turned off (as in, no exploration), or maybe better, run a Linux live session off a usb stick or dvd. I recommend LinuxLite.

I currently have two external hard disk drives I am having major problems with. One is a SeaGate Free Agent and the other a Hitachi which seems actually to be a Western Digital internally.

Both of them have recently stopped working. When I say stopped working I plug them into the USB port and both of them spin and light up but they continue to spin and never mount or connect properly. I can see the Hitachi is making some connection when I look in syslog but I don't know what to make of it.

I have attached segments of the syslog where the Hitachi was plugged in and then removed. However nothing to report from the syslog when the SeaGate was plugged in or removed.

The Hitachi was plugged in at about 11:03:15secs and unplugged at 11:06:15secs. I plugged it in again at 11:07:05secs and unplugged it again at 11:10.

The SeaGate is under warranty but I am concerned about sending it in with the personal data on it. I have tried using SeaTools suggested by SeaGate but it does not recognise the drive. Are then any other ways I can retrieve the info of this drive or at worst ensure all data has been removed before sending back for a Warranty Return?

The Hitachi is not under Warranty but the supplier has offered to replace it. Again I would like to do everything possible to retrieve the data on it, or at worst ensure everything is deleted.

I have also tried plugging both of the drives into my girlfriend's OLD Sony Vaio but it did not recognise either of them as well.

First of all, hello everyone!

I have a Dell XPS laptop and use an 80 GB external hard drive for storage. I actually found a site that has the drive which can be found here:
Toshiba (MK8032GAX) 80 GB IDE Hard Drive Product Reviews and Price Comparison -

But I am running out of space and was thinking of buying a new drive, say at least 250 GB.

I checked with the local computer store and they had 320GB for CAD 72.00, which I found quite reasonable.

The only thing is I am not sure if I should get SATA or IDE, which the guy at the store asked me and I had no idea what the difference was. I think the one I have right now is IDE (it says on the site I posted above) but I don't know much more than that.

My main concern is speed, as I will be using the new one to store movies and it would be better if I could just watch the movies straight from the drive rather than having to copy it onto the pc because the speed is too slow.

Also, as I have a laptop, it would have to connect via a USB port, so I would need an enclosure (or hard drive box), which I am aware of!

So any advice on would be much appreciated

Answer:External hard disk drive?

If you have USB 2.0 you have a max of 480 mb/s. Sata gives you either 150 or 300 mb/s and IDE gives you either 100 or 133 mb/s.

Long story short use Sata because it will use more of the available 480.

I purchased a Lenovo G450-2949 about 2 years ago with Windows & Home premium.  Shortly after the warranty expired it experienced a hard disk failure.  I replaced the disk and reloaded Windows 7.  The disk failed again a few months later.  I replaced it again and loaded Windows 8 on the machine only to experience another failure a few months later.  The machine now runs but does not shut down properly causing a boot failure requiring depression of the "f1" key to restart Windows.  I get regular messages that disk failure is imminent and suggestion that I backup and replace the disk...for the third time!  Can anyone help with this issue??

Answer:Repeated Hard Disk failures

It sounds like the cable to the drive might be going bad.Have you checked in on replacing it?Also, after checking the specs on this system, for the money that you have laid out on HDD'sYou could have possibly bought you a new 64-Bit 8GB system. (Just a thought).However, back to the issue.Check the cable going to the drive, as I seriously doubt that the drives are all going bad.This sounds like either:Cable (or) Motherboard issue.Also.The drive that you put in the system, does the BIOS recognize its full capacity?If not, then that could also be the cause of the issues, as if the BIOS does not recognize the full capacity, then that will certainly cause Windows to act up.Carrzkiss

1TB external hard drive is spinning when turned on, however my laptop is not registering the HD properly- previously it would come up with the hard drive name (G: VERBATIM) however now it just says G: Local Disk and comes up with the error message "One of the USB devices attached to this computer has malfunctioned and Windows does not recognise it".

It emits a tone when the HD is removed so obviously it is acknowledging the device, and it does still work, but it just isn't opening at all. Whenever I go into Windows Explorer and attempt to access the drive (or even just right click on the drive) Explorer freezes and I have to reboot.

I am running Vista Home Premium SP2, however the same problem is occurring on an XP laptop. Ideally I don't want to lose what's on the HD, there's about 400GB worth. Much of this is .avi's though, which going by other threads could be a factor?

Any help would be much appreciated.

Answer:Windows Explorer crashes when external hard drive is attached/accessed


Normally in this situation I would recommend that you went into the Device Manager console and tried to uninstall then re-install the driver for the hard drive; but since you experience this on another machine as well it seems as though there are one of two possible causes - either the filesystem may have become corrupt to some extent, or the PCB in the external enclosure has developed some sort of fault. I would say try and take out the hard drive if possible (and if you don't mind potentially voiding any warranty that may remain), and install it either in an available desktop or another external enclosure and see whether or not you can access your data. If you cannot I would say the cause is the former unfortunately.

Hope this helps.

about an external hard disk drive. I don't know which ones are recommended. I have no specific requirements, but it has to have about 500gb - 750 gb of storage. I don't need to bring it everywhere. What brands are recommanded and which ones are NOT recommended? So it's important that it is reliable and won't easily break down. Also what other things should i consider, is there any software included that may be handy?

These are available in the UK, the comapny Inuse has specials when these prices come down again.

I've got a WD My Book external drive which has been working fine for about a year, but now the drive does not appear in Windows Explorer.

Sometimes the drive letter will appear, but for no more than a few seconds. When it does appear you can browse the folders/files on the drive very briefly, but then Windows Explorer completely closes (which seems very weird as even if you unplug a drive that you are browsing I would expect WinExplorer to stay open and just flick back to the C drive or to Control Panel).

Also, when the drive is plugged in, you get the popup near the system tray saying "this is a USB 2.0 and would run faster if plugged into a USB 2.0 port...." but it is plugged into a USB 2.0 port.

- The power light on the front flashes at a constant speed, rather than the sporadic flashing you normally get when the drive is active.
- I'm running Windows XP
- I've tried plugging the drive into a different machine and same thing happens
- I've tried using a different USB cable to connect it.

Basically I'm pretty sure the data is still on the drive but I need a way of retrieving it. Can anyone help, please?

I just tried cleaning up my hard drive to conserve resources. I have a Seagate external drive to keep regular backups. Problem is that I've uninstalled several useless programs and emptied out most of the needless documents that wasted space. My HD is 111 GB. I've used almost 70 GB. Uninstalling programs didn't help much. Any suggestions?

Running on vista
I'm having problems using my external hard drive. When powering up it comes up with two windows suggesting I should run scan disk on the drive. Both the windows pop up at the same time, one behind the other. Running scan disk from either of these options fails to work properly (them seem to interfer with each other)
When booting the PC with the external HD already turned on a going to it in My Com. and using the tools there it gets about 1/2 way through and seems to stall.
I can't seem to run a disk scan on start up for the external drive, only for the hard wired in drive.
Having the disk on in the back ground does seem to interfer with windows operation even without me activly accessing the disk.
I'd rather not scrap the disk as it has a lot of music on which i don't fancy losing. With a bit of mucking about I could pull these files off onto the C: drive, but the external drive seems to stall when doing this 9making the operation less than practical)
Any ideas?

If someone would walk me through running a disk checker upon start up that would be fantablous. I'm running vista upgraded from XP (does this make any difference?)

Answer:Check Disk on External Hard Drive

Sounds like your drive has a bad sector or two. Let scandisk run; when it stalls it means it is hitting a bad sector, so it will go a lot slower, but when it finally finishes the bad sectors will be marked on the disk eliminating the stalling problem. Once this is complete, copy all of the data off of the drive so that you have a backup in case the drive fails later on down the road. Sometimes the drive will continue to run without any further issues for a long time, but if it starts getting bad sectors soon after, then it's probably on its way out.

Hello again,
I had a disk problem last week. I started to get disk error messages about disk0, which is I think the hd with winxp on it. My pc froze and I had to restart several times. Later the same day I started to get error messages about disk1 as well, which is my second hd.

Also, I was using a trial copy of eset internet security, which started to give error messages too. Then I noticed that one of the svchost processes running was using 20-30% of my processor, which caused my pc to lock down after a while. I didn't know what caused it all, so I wiped c: and did a clean install of winxp and later I did that with the first partition of my second hd as well.

Everything went well for a few days. A colleauge of mine gave me a copy of Norton Internet Security which has a 90 days trial period so I installed that one instead of eset.

But since yesterday my problems have returned. Disk0 is doing fine now, but disk1 seems to be malfunctioning. The second partition, on which I had a lot of important files, is not accessible anymore, but also the first partition, which I formatted last week and which was almost empty since then is giving error messages in the event viewer. The message I keep getting is that there was an error during a paging operation on disk1.

I am very puzzled. How could two disks break down at almost the exact same time? What was going on with svchost? If I had a virus how did it come back after I wiped c: clean and reinstalled windows? I ... Read more

Answer:Hard disk failures and paging errors

Is using internal hard disk in external enclosure risky in terms of loosing the data?

Is using internal hard disk in external enclosure reliable to use?

kindly let me know as there is a vast difference in the price of these hard disks. The external hard disk is costing more and if i use internal hard disk in external enclosure price is very much reduced.

my only concern about using internal hard disk in external enclosure is the reliability.

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.

I recently upgraded to Win 10 from Win 7.  After using the computer for a few weeks, it refused to boot to WIndows.  I was able to start it and scanned it and found disc errors and opted to revert to Win 7.  In the process, something got fouled and now the computer won't boot.  I've tried to back up the computer via the setup (F8), but that failed multiple times.  So, i removed the hard drive and got it to run/work in an external hard drive case.  I've scanned it multiple times and it appears to be OK.   Is there a way to create recovery disks from the hard drive now that it's out of the laptop?  In other words, is there a utility on the hard drive that allows me to create the one-time revocy DVD to reset it to factory specs? The computer is just out of warranty, so that's not an option. Thanks in advance,Tim

Answer:Recovery disk creation from external hard drive

Hi Tim, Unfortunately, the recovery media creator utility would need to run within the OS on the drive that contains the recovery partition. A couple of options you could consider are. 1.  Order a replacement set of Recovery Media from HP on the link below. 2. If you don't mind staying with Windows 10 and as long as the previous installation of Windows 10 had activated Ok after the upgrade from 7, you can just create installation media on another PC and perform a clean installation as detailed in the guide on the following link.  Note: At the activation screen, select 'I don't have a Product key' - Windows will activate automatically once the installation has completed. Regards, DP-K

I just recently backed up my desktop PC hard drive to a disk image on a second hdd using Macrium Reflect software. However, since I've never tried restoring this data, I really have no idea whether it will work should it be necessary. Would it be practical to do a 'test' restore to an external hdd (I know these are relatively slow, but it's just a test). I only have about 70gb total including WinXP Pro SP2. I simply want to confirm that the restore will actually work. The external hdd's ultimate use would be to simply host disk images.

Historically, I've only backed up what I considered critical data to a second hard drive. I was willing to reinstall OS and programs on a new drive if it ever became necessary. However, since getting a notebook, I was faced with the prospect of having to restore from a set of OEM recovery disks (WinVista disk not included separately) which would take forever as it installed tons of factory bloatware and other crappy stuff that I would end up having to remove.

I finally decided the time was right to back up both computers to disk images on an external hdd since this seemed a viable solution to avoiding the notebook recovery scenario. The entire purpose of this drive would be to archive disk images from both computers, with my desktop PC's second hdd used to backup the external drive.

This seems like a logical game plan, but am I missing any potential pitfalls? Opinions welcome!

Hey everyone,
I just purchased a new external hard drive for my laptop. I have a Sony vaio, and the hard drive I bought is a Micronet Platinum XL 500gb. I turned it on and it didn't show up in My computer so I went into the disk management and noticed it was not activated. I activated it and then still nothing.

That was obvious because the drive had not been formatted. So I clicked create new partition and started formatting it. All was fine, it was late so I went to bed, got up in the morning to see how it completed and it said that the format was NOT successful. Now it won't show up in My Computer, nor will it show up in Disk Management. Should I just create a WIN98 bootdisk and format it from DOS, or is there something else I can do?


Answer:External hard drive not showing up in Disk Management

If it won't show up, I don't see how you can format it in DOS.

Anyway, check out Device Manager and tell us more.

I'm currently using a Samsung NP-QX410, and I'm trying to install an external hard drive onto the laptop so that I can backup the data.

The hard drive is a Western Digital Scorpio 750GB
The hard drive enclosure is a Vantec NexStar TX 2.5-Inch SATA (I know it's cheap. That might very well be the problem).

When I plugged in the hard drive into the USB ports (I've tried all of them), the light on the enclosure lights up and I can hear the hard drive spinning. When I look around, I can't find any signs from my laptop that a hard drive has been plugged in (or that anything at all has been plugged in for that matter). After some digging I found out it's suppose to appear in the Disk Management page, then create a partition and do a few other things with it.

My disk Management shows no signs of the hard drive though. All it shows is Disk 0 (the basic disk) and CD-ROM (for DVD's).

To me the problem just looks like I just bought a cheap enclosure, but I'd rather ask to make sure there isn't an obvious step I skipped. If anyone has any ideas I'd really appreciate some help.

After about a year of use, this window came up on my screen with a tab in it Perform System Maintenance.I decided to click on the perform tab. It subsequently said that DISK VOLUME ERRORS WERE DETECTED.

I was advised to run CHKDSK and I did so twice over a 2 week period. CHKDSK took ages to finish its 5 stages. It then restarted my computer automatically. When windows fully booted, I ran System Maintenance program again and disk volume errors were still detected.
I subsequently realized that when I disconnected my USB 1 terabyte external hard drive and then booted my computer, no disk volume errors were reported when I ran the Perform System Maintenance program.

My internal laptop hard drive is a Hitach HTS725050A9A360 and it recently started to get bad sectors. Given that my laptop is under warranty, I decided to ship it to Sony to have it replaced.

Also you can download the manufacturers diagnostic tools - most from majorgeeks.

I have a Dell Vostro laptop running Windows XP Home SP/3. I use it for business (ACT database, Oulook, Word, XL, web surfing) and only a little personal use. It is not loaded with junk and I intentionally keep it very lean/clean to minimize possibility of tech headaches that could get in the way of business. I backup data to a flash drive, but having had a hard drive crash several years ago know that data back-up is but a fraction of the issue. The time it takes to reload software is a pain. So, having read many posts here am preparing to buy an external hard drive for back up. I have also read about imaging and that I can recreate my environment via that path. All that sounds excellent, except I don't know how to create a boot disk, what drive to buy, what software to use for the imaging piece, and how to keep it all VERY simple. By the way, I boubght this laptop in Dec. 2007 and have only used 20GB of a 100GB hard drive. That may go up as we bought a new camera that has digital video and I will be using the hard drive to store those images as well. Suggestions, step-by-step stuff, warnings, etc. would all be a tremendous help.


Answer:External Hard Drive & Disk Imaging basics

I would recommend that you purchase "Acronis True Image Home 2010."
It is a very user friendly program that is pretty simple to use for someone not experienced in backup and imaging. You could create an image of your hard drive (cloning) on a regular basis (weekly etc), and use that image (ISO) to restore your hard drive back to the "original" condition in case of a disaster. You'll only need a second drive with ample space to save the image to.

It's also great for when you decide that you want to increase your disk space by purchasing a bigger hard drive.

If you need any assistance using it, I'm sure we could assist you here. Once you have made a couple of images of your hard drive, you will get the hang of it!

I have included a link to the PDF regards!

Hi, sorry if this has been posted before, but I searched so many threads and none of them seem to apply to my exact situation (they all have the usb showing somewhere).

My usb/external hard drive, isn't showing up anywhere. Not in my computer, disk management, device manager or by doing cmb > DISKPART> LIST DISK. The laptop does make a sound when i plug in the drive however but the autoplay doesnt come up, nor can I find it anywhere. I've also tried switching everything off, tried different ports, checked youtube videos, followed lots of different instructions from so many threads, but nothing is seeming to work.

The problem began when I ran a system restore this morning, I then noticed the usb problem and cancelled the restore (to set it back to before the restore was done) but this didn't work. The problem is also the same with the dvd drive. On device manager both the dvd drive 'link' and a usb 'link' both have yellow exclamation marks next to them. Please can someone help me, I would be so unbelievably appreciative and grateful. I have been searching for hours, trying loads of different things but I just can't figure this out. Thanks so much!!

Answer:USB/External hard drive not showing anywhere (my com, device man, disk man, etc)

I assume that if you start without the 1TB HD that everything works normally.

If this is true, when you connect the 1TB HD, do you get any indication that you have added new hardware? You should.

Is your connection to the 1TB HD via USB?

Never mind. One of your images shows that the Seagate is recognized. From that, I conclude that the USB interface is good

I have all my work files on a portable HD drive which enables me to share my work between my desktop and my laptop. My portable HD drive has to be named D: drive due to the huge amount of special custom templates and formulas I use in my daily work. Unfortunately the software I use is old fashioned so I cannot change the drive letter. Because my old laptop crashed I've now got the new IdeaPad V570 so I was going to change the disk drive letters when it dawned upon me that the Lenovo D: drive is filled with drivers, fingerprint, and One-Key Recovery software which I probably can't change the drive letter on. What can I do?


Go to Solution.

Answer:IdeaPad V570 - I need my external USB Hard disk to be the new D drive

rasj, welcome to the forum,
does drive management show drive D as being a logical drive?
On an U550 I have here I took a look and D was a logical drive, it contains just one folder called Drivers which looks to me like a repository should there be a need, during a support call or something, to roll back to an original driver and also to save a bit of space on the C drive
Anyway, I went ahead and changed the drive letter and haven't have had negative effects; system runs and also re-boots without complaining.
The V570 is not an U550, but my guess is the installation style is the same.

I'm 90% sure that it shouldn't make a difference, that it doesn't has to be a SATA / SAS internal slave drive for you to create that drive image. But I never create a win 7 disk image on a USB Ext. hard drive before. Has any1 done it? Any difference than creating on a SATA internal drive?

Answer:Can you create your disk image on an external USB hard drive?

No difference.

I've done it with Clonezilla and imaged my laptop's hard drive to an external 2TB hard drive. I booted up into Clonezilla Live at bootup, restored the image to the laptop's hard drive, restarted and booted into the OS without issue.

Probably only difference I have to say is noticeable is the transfer speeds. Internal SATA hard drive probably would have done it faster than a USB2.0 connection to the external hard drive.

I have a Simple Tech Pininfarina 320 GB external hard drive that is no longer recognized by two different PCs, even under disk management. When plugged into the USB, the PCs do try to install the driver, but fails. It is recognized under Devices and Printers as Unspecified and with the information Model-Simple Drive, Category - Unknown, and Status-Software is installing for this drive. The troubleshooter searches for a driver, but does not find one. Basically I get the information that "There is a problem wiht the driver for USB Mass Storage Device. Reinstalling the driver might fix this problem." But I cannot find a driver for this hard drive.

Can anyone steer me in the right direction?

Thanks in advance!

Answer:External hard drive not recognized in Disk Management

The system is telling you that there is a problem with a USB driver, check in the Device Manager for any yellow warnings. Under Universal Serial Bus Controllers you will see a driver for USB Mass Storage Devices, right click and uninstall it then reboot, Windows should reinstall it, or go to the motherboard's manufacturer's site and download and install the latest chipset drivers..

There are two other possibilities, the hard drive has failed or the circuitry in the enclosure has develpoed a fault.

Remove the hard drive from the enclosure and (if you have access to one) hook it up to the internal connections of a dektop PC. Or, purchase a USB Hard Drive Adapter (about ?10) from a computer store or eBay and then plug it into the USB connection on any computer and see if you can then access the drive.

Hello, i have a problem with the disk space with my external hard drive.

My external hard drive had 698gb in total.

I wanted to install Linux Fedora along with my windows vista but it said that my hard drives (internal and external) need shrinking to get disk space for fedora. I went to disk manager and i did shrink my internal C drive but it was only 2GB. So i tried it with my External drive but it didnt work.

Now in disk manager it says that the hard drive has 698gb in total but in MY COMPUTER it says that i have 349GB in TOTAL!!! Please help? because i lost lots of space!!!!

Here is an image:

Answer:External Hard Drive disk space problem

What I'm guessing is on the disk management window obscured by the properties window is two partitions on Disk 1. Presumably you've shrunk the original NTFS partition and created an extra partition to install Linux to. You'll need to delete that partition and resize the NTFS partition to use the extra space.

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)?

Answer:Solved: External hard-drive:...format the disk in drive F: before you can use it.

Hi Everybody

Here is the scenario:

I was trying to remove the pre-installed Windows 8. I figured I should create a backup in case I ever have to go back to the piece of junk software. Anyway, I plugged-in my external hard drive to make the backup...

Here's the mess up:

It said 'formatting drive'. Within two seconds, I cancelled the operation and removed the hard drive.
Now, when I try to access it (tried on 3 other laptops), it just shows the Hard Drive as Recovery Disk with some 20MB data and total 30 GB space.
Disk management shows 890 GB unallocated space.
It's a seagate 1TB backup drive. There was nearly 500 GB of data on it.

Do I need to use some data recovery program or is there another way. I don't think an entire hard drive can be formatted in 2 seconds.

Can someone please help. I can't stress enough how important the data on the drive is to me.

My laptop is a Dell Latitude D830 running Windows Vista.

I've bought a Freecom USB 2.0 Hard Drive XS 1TB (Model Code SSYBBA) which came FAT32 preformatted. I wanted to reformat to use NTFS so I plugged it in to my USB port. Opening Windows Explorer, the drive was picked up as G:\ and I could view files on there and copy and remove files so I knew the disk was working OK.

I started reformatting by right-clicking on the drive letter and selecting "Format" from the menu and select NTFS and kept the default settings. After an hour I cancelled the formatting (clicked Cancel) and a message popped up asking me to confirm, so I did.

Since doing this, the drive is now no longer recognised and doesn't get a drive letter assigned. I've tried rebooting, reconnecting and checking in Disk Management and it just doesn't appear (although is powering up when the laptop starts). Also, Device Manager doesn't show it. Screen shot of Disk Management attached.

Can you tell me, how do I get the drive letter back to restart reformatting?

Thanks in advance for your help.

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?

I have tried connecting it to different computers and it still comes up with the same message that the external drive is write protected.

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.

When I plug in my WD "My Passport" 1TB hard drive, I can hear that a device has been connected, but when I open explorer the name's been changed to Local Disk (E and I can't perform ANY operation on it like open it, check properties or scan with an antivirus. I can't even eject it. Also the laptop slows down considerably and internet becomes too slow to open any page.
I tried running "chkdsk" and the data recovery software "PhotoRec" on it but it just keeps scanning for hardware and even after leaving it for 6 hours, it got nowhere. I tried opening "Disk Management" but even that keeps loading forever. A few times after the problem started, it told me to format the drive to be able to use it, but now even that message doesn't come and I'm not even able to format the drive(though I prefer getting all my data back, but it's better than spoiling the HDD).
The drive is physically fine as I kept it very carefully and I can hear the smooth rotation of the disk, plus there are no 'clicking' sounds coming out of it.
