Removing references in modprobe.conf and modprobe.preload for
ide-scsi is also neccessary. Consider this advice temporary as
Mandrake (current 10.1 devel) is goin back to ide-scsi for IDE CD
devices. Early 10.1 (2.6.5 or .6 kernel) is already back to it.
Contrary to the questionable Mandrake move, this 'last minute'
change to magicdev for 10.0, I'd suggest doin a urpme on it an
then runnin 'supermount -i enable' && 'mount -a' Supermount is
mature, magicdev is alpha, and has known problems. I find
supermount-ng as implemented in current 2.6.x kernels to be
flawless.
Another mistaken Mandrake move, but can easily be turned off or
removed is tmdns.
John, check that 'll /dev/hd*' return drives numbers suitable
for your CD drives(s). Make sure fstab also reflects the correct
device, ie, hd*, not scd*. Check /etc/ modprobe* files to be
certain they don't call ide-scsi or scsi host adaptor. I'm
sort'a thinkin your fstab (Mandrake bug) doesn't accurately
reflect the device connotations. If my advice doesn't work for
you post the results of
- 'll /dev/hd*' and also /dev/scd*
- Your /etc/fstab file.
- 'cdrecord -scanbus' and 'cdrecord dev=ATA -scanbus'
- Your modprobe* files
Come to think of it, post your kernel version ('uname -r') and
the above to the list before makin any changes.
Prepare to forget, undo/re-learn all this when you upgrade to
10.1, or a newer kernel than 10.0 came with.
In fairness it's not all Mandrakes doin. Currently Linus and
much of lkml is at odds with cdrecord and it's author. A fresh
install rather than an 'upgrade from' probly would'a avoided the
CD-RW problem tho.
