OT: hard drive making weird noises

Ok, I've googled but have not turned anything up, so I turn to the experts on the list. I have a 60GB IBM hard drive (can't get at the model number and don't want to power down to do so right now). Every once in a while I hear it make the most disconcerting noise. It sounds like a <chirp> followed by a <ka-clunk> followed by another <chirp> and then another <ka-klunk>, all in the span of no more than 2 seconds. It sounds as if its skipping a heartbeat or something. What the hell is going on and how do I defibrilate it? I had a similar problem long ago with another brand of hard drive (Maxtor maybe?) and it required some sort of firmware upgrade that fixed it. I checked into this problem a while ago but did not find anything on IBMs site or through Google. I do NOT need another hard drive crash right now :( -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *
