I kept getting these too. Right now after twiddling with drive flags I
have it stable at Ultra/33 but this is a real drag as the drive is ATA/100
and the card is a /133! Moreover, I only have a single IDE disk.

Most of the errors I observed were on very long files, which unfortunately
happened to be my MySQL indexes. I also saw them on the very long webserver
log, and a number of them were unrecoverable. :-/

At the moment the beast is calm, and fortunately the backups were intact.
