I have been looking at it with the KDE interface, I was trying to find where
the blasted CD was mounted in the system. I am running SuSE 10.1 and
it shows the CD as being mounted under /media/dev/hdc, but when I go
in there to find the thing and look at it with other tools it is not
there... So it
is being mounted elsewhere, and I am not finding the thing...
I am going to have to look into this more, I have until now never had a CD
that I could not find mounted in one of the common locations, but this is
not working out that way. Usually the CD's are mounted under /media,
and that is what it is telling me but when I go in there the bugger is not
there. So I am going to have to figure out where it is mounting the thing, I
assume that it is mounting it differently because it is a audio CD.
