LaCie hard drive is not recognized by Windows Vista

I recently upgraded my OS to Windows Vista Ultimate. Since then it has not been able to recognise my Lacie Hi Speed USB 2.0 Hard Disk. It says that the Hard Disk is compatible with Vista yet I cannot find a solution. Any help would be appreciated.

    My drive was formated to Fat32 so that I could use it download video from my Sanyo HD cam. Lacie says that the drive should work as is, but I have the same problem.

    I have a WD1001FALS 1tb hard drive that I move around from one computer to another. It is formatted FAT32 (on my MAC). Now, I move it to the VISTA Ultimate PC and it only shows up and "unallocated space".

    Can you run a FAT32 partitioned hard drive on Windows Vista? And if so, how??

    This is not running and OS, only backed up files.

    Many Thanks.

Well my hard drive is formatted in NTFS as this is how the instruction manual told me to. It's ok...i wasn't liking vista all that much so i rolled back to X. Cheers for the help anyway guys.

Thx for the reply. However, my the solution for me was easy; just plug the drive into another usb port. I guess the initial port I used was picky. My Vista 64 does recognize Fat 32.

Sata drive is not recognized by os during new install

When installing XP or Vista you get the option to load third party drivers for unknown devices. I think it's F6 just after the start of any version of Windows, once you press this you will have to supply the drivers for the Windows installation. This will make Windows recognise the hdd from then on.

PC no longer recognises LaCie drive

Hi Katya!
There are several possible causes for this. You didn't specify if you're running Windows or Mac so I apologize in advance if some of the information I provide does not apply.
  1. If you recently performed a Windows Update, there's a patch to fix your issue;
  2. There is a firmware upgrade for your external hard drive. It is located here:
  3. If the above solutions don't solve your problem, you may try uninstalling the device and reinstalling it. This should clear any communications errors it may have
I do hope I was able to solve your issue. I wish you the best of luck.

Acomdata external harddrive is not recognize on vista

I had a similar issue with windows 2008 and windows 7. the drive lost all its info and had to be reinitialized under both of those O.S.'s..
You can try that as long as it doesn't have any data you need.. Once you do that the drive will work and you can start using it. The file system under vista and above is slightly different than xp.

Can't access my lacie external hard drive

I would first plug it in to a different PC, this will tell you if the problem is the Lacie or Windows Vista.
if it works on a different PC then remove it from Device manager or go to the Lacie website for Vista updates.

If it does not work on a different PC then there are 3 possibilities
1. the drive got cleared data lost
2. the enclosure is bad (I would bet on this)
3. the drive is bad

purchase a USB enclosure, remove the drive and install it in the new enclosure plug in and test.

Hope this helps
thanks for rating
