I used to be able to plug my memorex 256mb storage drive into the front of my pc and use it. Yesterday I had an external hdd hooked up instead. When I finished with that, I plugged in my memorex unit and nothing. The safe to disc. icon showed it there but "My Computer" does not. When I click on safe to disc. and hit properties, it says device is working properly. It says USB Mass Storage device at location 0. Any ideas? I'm running windows xp sp1 and this is a work pc with only E drive avail as my usb drive.
