Most versions of the Linux ISO9660 filesystem driver support read-write. Did you specify "-o rw" in your mount options? Here is what I would do to get a huge ISO image file mounted read-write: mount -t iso9660 -o loop,rw /tmp/huge.iso /iso Hope this helps.. -- Jim Ockers (ockers@ockers.net) Contact info: please see http://www.ockers.net/ Fight Spam!
