I just moved one of my other hard drives back into my machine. It's a 120 GB hard drive, but the computer reads it as 31.5 GB. Is there a way I can get my computer to recognize the true capacity of this hard drive? Thanks.

This is what happened to a HD (120 gig IBM) froma Mirror Door Drive G4... weird ****. Half of it died.

Run either the disk utility and see what it says under the smart information (I forget the exact wording as I'm not on my mac now)

If that isn't helpful then run AHT cd and see if it comes up with anything.

sounds like your drive is going south.

Double check the pin settings. I had one drive that for some reason had a pin setting that limited its size. Maybe you applied the jumpers with the drive upside down? (I did that just the other day-- duh.)

The drive is not "going south" -- when hard drives die, losing part of the capacity (but otherwise working fine) is not one of the failure modes.

It's either a misplaced jumper (as chris v suggested), or a run of the mill incompatibility (they're rare, but they do happen).

Thanks for all your help!

What I originally did was take it out and put it in my PC after zeroing it on the format because I wanted to replace the aging 40 GB hard drive in there. By that process alone the drive shrunk, and there's some sort of incompatibility there that may have triggered the shrinkage.
