Computer won't recognize Hard Drive out of the blue...??

[PHeNoMZ28]

Something terribley wrong must have gone on inside my computer last night, because when I woke up this morning, my computer lost my H: :disgust: There was an error message that said "Error: H: blah yada" and I really thought nothing of it and just clicked "OK"... then I checked my drive later in the day because I wanted to listen to some music from it, but it wasn't there! Since then I've tried everything I could think of to get my computer to recognize it, but to no avail. My slave drive on the same band is recognized, but my H: (the master) just can't be found. Do any of you have any experience with something like this? I don't know what I could have done because it just happened in my sleep...

Any help is appreciated.

For what its worth, its a Seagate 160 gig drive...

Is it picking up the drive at all? Is it seen in the BIOS? Is it seen in your disk management? You may just have to do a quick format on it and get some file recovery.

Unplug & re-plug the Power and Ribbon cables to the drive.
Somtimes they vibrate loose, or get a little surface oxide at the contacts.

I've unplugged and replugged it in multiple times, nothing is showing...

BIOS never showed it before either, even when it worked. BIOS only shows my IDE1 master and slave and IDE2 master and slave. It doesn't show me my IDE3 and 4 which I have this hard drive hooked up to.
