In disk management, make a partition there, format it....
My problem is that my external HDD shows up in the Safely Remove Hardware area as a Mass Storge device but it won't appear in the My Computer screen. It had previously [worked] but in an attempt to eliminate residual system files (it used to be a C:/ drive in my old laptop) I wrote zero's to the thing. I suppose that was a bad idea seeing as it basically disabled the drive but is there a way to get my machine to recognize it again? It spins up and everything it just won't show up as a letter drive.
System I'm running: Dell XPS M1710 w/Windows XP
HDD in question: 2.5" Toshiba drive inside an external USB enclosure.
