Configuring an atapi CD-RW under Debian
I'm running Debian Sarge and have a CD-RW (atapi) drive installed that I
want to be able to record to. As I understand it from the various help
pages around on the internet, I need to stop it being recognised by the
system as IDE (it is actually on hdc), and use a SCSI emulator.
I've installed the cdrecord package, and attempted various changes to config
files, to start with I got nothing from the output of cdrecord -scanbus, but
now it appears to show the drive up correctly, but I still can't record
anything. More to the point, the 'cdrecord' command seems to solely deal
with writing music tracks or ISO images - I'd really like to mount the CD-RW
as an proper, ordinary filesystem to do backups. Can I do that and what do
I need to specify as the filesystem?
Plenty of output from various commands / config below if you can point me in
the right direction.
Thanks in advance,
William

(typing eject /dev/scd0 works, I can also read from an ordinary CD-ROM if I
mount it)
