:I am realy supprised that you had to use the IDE-SCSI emulation to access

:cdrecord -v dev=/dev/sg0 speed=4 -isosize /dev/hdc

:CDrecord reads from the IDE CD ROM just fine for copying CD's. The only

Elifyno. I admit that I had no luck with the command line, and so was
working with XCDRoast, which has no built-in support for ATAPI in its
latest build.
FYI, for anyone who does what I did, you must modify /etc/fstab as
well -- /dev/cdrom is no longer valid; I had to change that to
/dev/sr0. And of course "eject" now always requires arguments...
