Hard drive stopped showing up?

[Kiamo]

One of my hard drives suddenly wont show up in "My Computer". Its installed.. I see it in the device manager. I removed it and it reinstalled fine. But its not there. Drives go C, E, F..
It just worked a little earlier and I didn't change anything. I've been using it for almost a year. I know its formatted right and all that...

Any ideas?

Try accessing it through DOS, using a bootdisk. If it still cannot be accessed, perhaps it needs to be repartitioned and reformatted.

Its formatted for NTFS, so I can't....
