It's probably a good idea to try and access a cdrom as root first.
Stick some cdroms into your cdrom drives first.
Then, if you open up a bash terminal window as user gary, and at the
command prompt type:-
(then press the return/enter key to complete the command)
You should be prompted for the root password.
Once you have typed this in and pressed <enter> then you should see the
prompt change from gary at ... to root at ...
If you don't get any error messages then you should get the root prompt
If you see the files on your cdrom listed then you have succeeded in
mounting your cdrom under Linux. The rest is then due to permission setting.
Once you have finished, you need to unmount this filesystem. This would
typically be the case when you finish using one CDROM and would like to
use another CDROM, you need to unmount the first one before removing the
CDROM from the drive. To unmount a filesystem (such as the one we
mounted above) type:-
Remember to type 'umount' and not 'unmount'. There is no "n"!
Then try the same with
If you get errors then post them to the list.
You should make special directories just for mounting devices, and leave
them empty. Technically you can mount your cdrom anywhere in the
directory tree, even a directory that is not empty. However, any files
in that directory will become invisible in the virtual file system. They
will still exist on disk, but you will be unable to access them until
the file system that obscures them is unmounted. For example, If you
mount your CDROM at /usr, you would not be able to access to most of
your installed programs in that directory as long as the mounted
filesystem remains mounted.
BTW it's best to turn off HTML when posting email messages to this list,
just send plain text please.
