It would APPEAR that Linux is trying to swap the drives somehow. CHS *does*
indeed stand for "Cylinders/Heads/Sectors-per-track." My suggestion would
be to make sure that you don't accidentally have the SECONDARY master on the
same IDE chain as the PRIMARY master. Also, do you have the primary jumpered
as Master? If not, and the "old" drive is still on the primary IDE chain,
then that would probably be part of the problem. Also, if I'm reading it
correctly, you're thinking that HDA should be your SECONDARY drive... IIRC,
though, hdA is your PRIMARY drive, so that information would be correct
(more or less) for your primary drive (do you have multiple partitions on
the primary drive, the 8447 Mb drive?) hdB is your second hard drive on the
IDE chain and hdC would be the third, etc....
That's about all I can figure.... Good Luck!
