This drive is too old to support even multiword 2 DMA. If you're getting
timeouts, and they seem to only happen when accessing certain files or
areas, then your drive has some bad-but-not-totally-dead sectors on it, and
the drive electronics are being slow about correcting the error.

This is becoming a FAQ, I think...
