I’ve used my usb freecom toughdrive on xp home for months, then the drive letter disappeared. It’s not in disk management either. When I reconnect it I get the new hardware balloon and wizard, and the wizard can’t find a driver (there wasn’t one, it’s plug and play), then the usb device shows in computer management as not configured correctly. I’ve tried Restore, a day at a time, but it makes no difference (a message comes up saying the drive letter is excluded from restore or was removed). Uninstalling from there then reinstalling brings me back into the new hardware Wizard loop.
There’s nothing wrong with the disk – it works ok with other computers. I should mention that there is an optional mains connection for the drive, computer seemed to get confused between when it was on mains and when it wasn’t.
Any ideas for a fix would be really welcome, i’ve got all my data on the drive!
