Make sure no program has a file open from it, or no file manager is looking at it, or no term or xterm is in it. And make sure you haven't done an 'su' with the *parent* shell in it. Happened to me tonight - I was looking *everywhere* and couldn't find it. Finally hit exit in an xterm and saw my user prompt there.

hello
you can also do a fuser -k /dev/scd0 and it will kill the process which is using the cdrom, be sure it is not your self, otherwise your session will be killed.

My post made no sense on re-reading the thread. Sorry, I don't know what the solution is.

Just check out that any file or directory from the mounted cdrom is not accessed by any application.... If it's so then just close the application to umount the cdrom......
