I've got a Sony CD-RW CRX230E on this machine, which until recently appeared
to be working ok. Now I'm getting a "No Media Found" when trying to mount a
data CD. When I first noticed this, I tried an audio cd, and that played ok,
but now I find that the cdplayer just says "no disc". Neither can I boot live
cd's now, even though the cdrom is first to boot from.

The drive is detected in the BIOS as master on IDE1, which is correct, and
dmesg shows that it's there on IRQ15, and KDE's info lists a load of
different stuff about the drive.

I havn't changed the cable yet, just unplugged, and replugged it from both
ends. When I put a disc in the green light comes on for a bit, and there is a
touch of HD activity, and another couple of flickers of the light.

Is there some CLI tool in Debian Etch, or Lenny that I can use to thoroughly
check out the cdrom drive?

Thanks for any suggestions, including telling me that the darned thing has
died.


I don't know if this will help you or not, but keep in mind that the
Linux kernel treats all devices like files, so you can just open a
terminal and cd to the CD (pun). Usually it will be /media/cdrom which
is a symlink to /media/cdrom0. In older systems it was always
/mnt/cdrom, but whatever it is, it doesn't really matter. Can you ls
the files on the data cd by doing:

ls /media/cdrom

?

It seems to me that if the drive can play audio CD's then it *should* be
able to read data CD's too.
