I was also using hdparm.
Yep. Sounds like mine. Expect I was using 2.4.7 as well as hdparm. Oops. The drive was a maxtor though. I don't think the IBM drives had any problems though. > I re-installed and went to a 2.4.5 kernel with the via/southbridge ide > driver.

For now I just got a 40g scsi to work on while I examine the trashed drives.
