Ok, for some odd reason my secondary "slave" hard drive just messed up on me.
It doesn't show up on "My Computer", "Device Manager", and BIOS. and it makes my Primary "Master" not show up on BIOS only.
and before it stopped working it, windows xp said some thing like. "Write Queue Failed". and a couple of days ago it did show on bios and Devise manager, but not on "My Computer".
its a Fujitsu, by the way.
and its 40gigs.
