Why has XP suddenly stoped recognizng my 2nd internal hard drive?

[pstokely]

I have two internal hard drives installed in ATA configuration. Suddenly, the 2nd internal hard drive, normally assigned "I:" has gone missing from my configuration There's something in device manager simply labeled "Disk drive". Has my hard drive gone bad, has my motherboard gone bad, or is it something else. Nothing important is/ was on that drive, but it will take time reinstalling the stuff on another drive.

1. Open it up and jiggle the plug

Seriously, the lack of a mechanical connection is the most likely problem.

2. Resolved this yet?

I've been messing with my "Services" and there are some entries in there that affect whether drives are seen - so some new things to check out, if the problem is still there.

Like this one, although I'm not certain - but worth checking to see if this service is running or not (Run > services.msc)
