I've begun to have a problem with my external USB hard drive (Maxtor 200GB). When I reboot, it disappears. If I open the Safely Remove Hardware, it shows up as a generic volume. If I remove it from there and unplug/replug the drive, it shows up. I have to recreate the share on it and it works fine until reboot. I can think of no update/install that has happened to cause this. I've tried removing all of the USB Root Hubs from the device manager but that doesn't work. Running XP SP2.
