I am attempting to connect a Lacie USB external hard drive to a laptop with Windows XP SP3. It appears fine in Disk Management with an Active and Healthy partition but it does not have a drive letter.
If I assign a drive letter I can view the files by opening the partition from Disk Management. I can also access the drive from the Command Prompt. However, the partition does not appear in the Explorer, unless I log out and back in. Unfortunately, if I restart the computer the partition comes back without a drive letter again.
I've tried removing all the USB devices in the Device Manager and then reinstalling but the problem remains. I've also tried connecting to a different USB port. I have not yet tried attaching the drive to another computer.
What else should I try?
