Hi, I have been noticing that the hard drive doesn't spin down like it should. I have already taken the steps of setting async and noatime to all the filesystems, so mere reads will not cause the hard drive to spin up if the data is already in its cache. After watching the hard drive light, I noticed that the hard drive was being accessed about once every 30 seconds. Suspicious, I checked the update daemon and sure enough, it flushes the cache every 30 seconds. So something out there is writing stuff. However -- I have turned off sendmail's automatic queue runs and the only other things going were X, fvwm2, and some xterms -- all of which were running telnets that were logged in to a remote machine. This isn't a big problem but it is a strange one. A bigger problem is that the last time I hibernated the system, it locked solid when I turned it back on -- the video was restored and then it would lock. I suspect this is due to either X running or the Ethernet card being plugged in -- I have heard that there may be some strange interference from either of these things -- so I need to do some more investigating yet. John
