This is how you should approach most problems, not just computer ones.

Yes indeed. When I code, this is the easiest solution. Being new to debian, I didn't know which program would be the easiest to test this with. Obviously I should have seen this.

OK, I think you are almost there. What you show above is almost what
you need. The thing is that you are now out of the disk group so you don't
have permission so read or write /dev/hdc. Use chmod to fix this the
prblem for /dev/hdc.

chmod o+rw /dev/hdc

Now try and run cdplay again.

Ahhh, I can't believe I missed this. I forget that UNIX/LINUX trates devices as files. It's rather embarrassing that I missed this but thanks Nick. I'm very grateful for your help.

See above. It makes the /dev/hdc readable and writable by everyone.

Email the list with the results (and please _don't_ cc me, I only
need the email once).

Sorry about that. Won't happen again.

Cheers,

Nick.
