Hmm... that puzzles me, although for no other reason than I'm not familiar
with how Maxtor drives report themselves. Having the BIOS-reported LBA
sectors not equal to the OS-reported geometry may not be a problem, but
I must defer to the experts on that one.

As an FYI just in case, the new libata-based driver will treat your drives
as SCSI drives, so you'll see the drives as sda, sdb, and so forth instead of
hd?.

Good luck!
