Not to worry. The "bee" has been a normal event here for years. I have no idea what it is but it's apparently harmless. My best guess is a drive doing some sort of alignment check. I have a Seagate 320, a Seagate 80 and an IBM 80. I sounds benign, lasts about 1 or 1 1/2 seconds, occurs totally randomly a couple of times a day, and doesn't affect anything that I've noticed. My dual 1GB MDD runs 24/7 w/o sleep, BTW.
FYI, if you hear the fan speed up much at all, try cleaning the intake plenum chamber in the lower front (aggressively with a tooth brush or similar and a vacuum upholstery brush). Get all the dust bunnies you can see. My temp went from 138 deg F down to 126 and the fan complains MUCH less now. - Peter PS: I find a bit of grog helps the nerves.

Hy! I am installing a new system for my powermac (and I am like bit on the edge with my nerves, because everything goes wrong), and I heard no such noise when I loaded the optical drive with my installation DVD. It seems that this sound poops up randomly. Well, I this computer is normally up for days, but iStat reads 46-49C temperature, so there should be no problem. I really hope that it is not something wrong with the PSU. Should I reset PMU? If so, with what command in the open firmware? p.s. I is it OK for the CRT monitor to be in standby mode for days? I really worry, because sometimes I leave the computer on when I leave home (it does some intense processing). My monitor is SAMSUNG SyncMaster 957p, some 8 years old. The image is of very high quality, never damaged (as far as I know), on the power surge.
