Schmidt) Followup-To: unix-pc.general Distribution: na Organization: Bolt Beranek and Newman Inc., Cambridge MA Lines: 27 I bought my 3B1 (2M/40M 3.51) 3rd hand about 3 months ago. When I first got it, it would whine occasionally, with about a 2 minute quiet period in between whines. It has now progressed to the point where it is whining/ warbling constantly. It is hard to localize the source of the sound, but I'm afraid it's the disk, since I can hear the fan running quietly in the back. SO, what I'm asking is a) has anyone had this happen to their box (and did it precede a major disk failure)? b) does the 3B1 have a history of bearing lossage in it's hard drives? and c) can any of you hardware gurus walk me through a simple diagnostic procedure to pin the problem down better? The machine hasn't given the slightest trouble since I've owned it. It has been up for weeks at a time. I keep hoping the noise will just go away... but I backed up the entire disk night before last.
