All of a sudden, Vista doesn't recognize my external hard drive anymore. When I turn it on all that happens is that Windows says that it's installing drivers, which it finishes, but the drive doesn't show up.

I installed some modded GPU drivers yesterday because Nvidia hasn't made a driver for my card yet. That's the only thing I can think of that might have caused this. I uninstalled them but it didn't help.

I really need a document from that drive by tomorrow because I have to hand it in to my teacher tomorrow.

Please help.

I guess you redefined that ol' excuse "my dog ate my homework" with "my Os won't recognize my external hdd ..."

Maybe a day late or so but you know u could always hook up your external to another comp.
