USB HD no longer recognized by Vista or XP

I have a 250GB drive I used on Vista for a year its now on an xp and worked now neither can see it when you connect it. Vista found it after many tries yesterday, so I hooked it up to XP with no success. Now on Vista again it can see the drive but not the files. It reports the driver is working fine. I need to recover all the files on here and transfer them to another HD if I can get it to read them like yesterday.

    I've tested on two PC's one Vista one XP, both have other USB hard drives connected and working fine. This one worked for about a year. Yesterday after much struggling I managed to get Vista to read it, I should have copied the files then but neglected to.

  • fasted_e Jan 04, 2009

    No software came with this drive, it's just plug and play. Vista recognised a connection in exporer but reports no files. When I unplug the USB and reconnect it reports USB device not recognized, yet reports the drivers for the device are OK?

  • fasted_e Jan 04, 2009

    Thanks Marked, changed the USB cable and opened in my computer, no fix, it still doesn't see it? Any other ideas?

  • fasted_e Jan 04, 2009

    Thanks coolguy 008. I'm testing on my Vista PC as it was originally connected to it and it was the only PC to find it after much struggle yesterday. Does you procedure work the same way on Vista or do I have to work off the XP?

  • fasted_e Jan 04, 2009

    coolguy008, can you repost you fix, I rec'd another suggestion but can't backup and find yours?

You can try to go to www.recovermyfiles.com
You can download the software and run a scan. The trial version allows you to see what files can be recovered. So dont buy the software unless it shows that you can recover your files.

    Of course it's only gonna work once the hard drive is detected. It sounds like a faulty drive and the only thing you can try to do is to save the data. If you cant get it to work even on another computer, you can try to contact Drivesavers (800.440.1904), Ontrack or you can google for other companies who specialize in data recovery. They're pretty costly, but if you're files are very important, it's the only way to go.

If you are trying it on different PC's i don't see all the USB ports on both computers being messed up. I would think it was something wrong with the Harddrive itself.

Do you hear it spinning when its plugged up and powered on ?

If you have access to the Administrative Tools( In Start/ Control Panel), go to Computer Management. Under storage, there is a Disk Management section. This will show all of the drives found by Windows. My Computer and Windows Exporer only display drives that are initialized and ready for use. Drives found and recognized by the PC are listed in Disk Management. They won't show up elsewhere in Windows until they are properly initialized. This comes in handy for troubleshooting because if a HDD is not found in Disk Management or found in Disk Management but not Windows Explorer, then you are having a HDD issue. If the HDD is found in both, then you are likely having a windows issue.

You could try removing/deleting the USB controllers from Device Manager and reboot. This will force Windows to reload the USB devices and drivers. You could also verify and/or install the latest MB drivers, which should include USB drivers.

And then there is the obvious stuff, like a bad USB connector in the PC, a bad USB connector on the ext HDD, or a bad USB cable.

Hi
Boot the pc with erd commander (the one with XP) with the hard disk plugged in, and so you should access the hdd, then erd has also a tool to administrate the plugin, uninstall all these hdd plugin you have installed, then reboot without the usb hdd plugged, and when XP loads, plug this HDD to another USB. This should force XP to install again the drivers (that generic from XP) that uses to work.

    1. In C:\Windows\System32\DriverStore\FileRepository I had two folders
    named "usbstor.inf" but each one had a different set of numbers
    attached to the end of the folder name. - could this be where part of
    the problem lies?
    2. When i looked in my C:\Windows\inf folder i discovered the
    usbstor.inf and usb stor.pnf files were missing - this definitely had
    to be an issue.
    Once I discovered these anomalies, I proceeded to copy the pnf and inf
    files from the most recently updated usbstor.inf folder to C:\Windows
    \inf. I then went back to the update driver wizard, pointed to the inf
    folder and what do you know but they all started working again.

    Worked for me!
    Hope this helps.

I had the same similar problem before. It was because the actual HD connector inside the enclosure was loose and was not properly seated hence not giving full contact to the little system board which transmit electrical signals to the USB port

If you try another computer and it doesnt work, there's a last resort option which is the following:

inside the case that contains the HDD is a normal HDD which has an IDE connector just like any HDD used on desktops. open it up take out the adapter board which converts it from IDE to USB and then use the normal HDD inside that has an IDE connector. set it up as Slave using the jumper diagram drawn on it and connect it on a normal PC as a second HDD, start your PC and you should be able to read and back up all data on the HDD.

after you're done, make sure to back things up on DVD's or CD's and make regular renewed copies of those DVD's or CD's so that you make sure your data is safe.

    did it come with an external power supply ? if it did, unplug the power cable from power socket and short the two or three leads on the power cable for 5 min while other side is connected to the HDD. this will discharge any extra charge on the capacitors inside the HDD electronics, then connect. it sounds funny but it works and happened to me with many USB devices. where USB DEVICE NOT RECOGNIZED keeps poping up.

There are several ways to retrieve data that has been deleted from a computer system, even if you've deleted them from the recycle bin or reformatted your hard drive.
When you delete a file, Windows only marks the file as deleted, but doesn't actually remove it from your system. Those files are only truly deleted (well, replaced actually) when other data is saved to the same location on your hard drive.
The reason our deleted files were recoverable is that no other data had been saved to those same places on the hard drive.
How to recover files that have been deleted: If you've accidentally deleted an important file or erased a folder containing files that you later realize you still need, don't worry. Chances are good that they're still on your system and in good shape.
You'll need a good data recovery program that can find files that have been deleted. I've tried a few different programs that claim to be able to do this, but have discovered that some of them are only able to show you what's still in your Recycle Bin. That's not much help if you've emptied your Recycle Bin, so I wasn't impressed.

  1. Delete a file or folder
  2. Empty out the Recycle Bin
  3. Run the data recovery program and see if it's able to find and recover the file.
I did this test with iRecover and discovered that it was able to not only find the test file I had deleted, but it also found hundreds of files from folders that I remember deleting several days ago.
iRecover is an advanced data recovery program that will help you recover data that was lost because of file system corruption, formatting, virus damage, partition deletion... or in my case - user error.
Here's a screenshot of iRecover that shows all of the files and folders it was able to recover after completely clearing out my Recycle Bin:

Hi,

Try connecting your drive to another USB port. Using one port all the time to connect and disconnect USB items a port can develop a range of files associated with configuring the USB connection. Some of these files might actually have been from your drive connected before, or some of these configurations could be from other USB items you connect to this port. Changing ports can often lead to an immediate good connection simply because ther are no conflicting configuration files. If this does not solve your problem, we can now entertain the next process to try.
THIS IS A BIG ONE. This is the last thing to do. Before you try this process, please complete a full back up of your system. This is important as the next step can have side effects you did not entirely expect. AND Second, you might need your XP Install Disk (not in all cases). What this process is about is renewing all hardware/software configurations relating to USB connections.

Here is what you do:
1. Right click MY COMPUTER
2. Select PROPERTIES
3. Select HARDWARE
4. Select DEVICE MANAGER
5. Select UNIVERSAL SERIAL BUS CONTROLLERS
6. Right click on each USB CONTROLLER and select Uninstall
7. Uninstall all entries
8. Reboot your computer
9. As your computer re-boots it will reinstall all USB connections it detects
THEN, when all other USB items have been configured and connected by the system, you then should try connecting your USB drive.

If these suggestions are implemented and you are still have connection difficulties with your computer, there are several other things to try. If you have another XP Computer you should try connecting your drive to another computer to see if the problem is a drive problem or not. If it still has this problem with the next computer, it maybe be a fault of the drive

IF YOU HAVE COMPLETED ALL the above mentioned and still have a problem, you should next contact the seller of this machine for further instructions of what to do next.

    I quote from you: "Vista found it after many tries yesterday, so I hooked it up to XP with
    no success. Now on Vista again it can see the drive but not the files." that is a faulty hard disk.

    If the fault is logical (bad sector, damaged FAT etc, you can attempt using dedicated software to access the hard drives. This often does not work.

    If the fault is mechanical (motor, heads , etc) you need to spend at least $600 to recover the files, as to open an HD with internal faults we use a special facility that is very expensive.

    The first thing to do is extracting the hard disk from the USB caddy enclosure, and testing it on a different enclosure.
    If you are lucky enough the control board inside the enclosure had gone faulty, and the hard disk is still good, with all files inside.

    If not, files are usually lost, unless you are prepared to spend some big money for the recovery.


  • Ginko
    Ginko Jan 04, 2009

    Well that was the truth, I fix this things for living.

    " This one worked for about a year. Yesterday after much struggling I managed to get Vista to read it"

    That is either defective controller board inside caddy, or faulty disk with damaged FAT, surface problem, logical error.

    Test the disk on a different caddy, or inside a PC, if it does read recover files, if it doesnt, well I told you.

    You can refuse it but that is the truth .

    Goodbye.

Lacie 250GB Hard Disk is not being recognized by PC (Windows XP)


Some PC's cannot deliver enough power to the USB devices to function properly through the USB port.
Does your Lacie hard disk have a power input connector if so conect a power adapter to it before you put it into your USB port.

Another alternative, get a powered USB hub connect it into your computer then connect the Lacie hard drive to the powered USB hub.
