in grub you should have the line:
hdc=ide-scsi hdd=ide-scsi
that is no append and no "" needed.
EDIT according to previous poster they are needed, hmm try both
one of them should work. /EDIT
if not what do
Code:
dmesg|grep sc
and
Code:
dmesg|grep CD
give as output?

hmm, what does
Code:
hdparm /dev/hdc
and
Code:
hdparm /dev/hdd
say?

keep trying.
