I bought a Western Digital 250GB USB external drive already installed into an enclosure. I have plugged it into both my XP laptop and my Vista desktop. Both computers do this:
1. Recognize that a mass storage device has been connected and installed the driver.
2. Show the existence of the device under Computer Management as "unallocated." (The XP machine says the snapin needs restarted (which I don't know how to do)).
3. Problem - Neither computer has assigned the drive a drive letter for me to access the drive.
Any help would be greatly appreciated.
