Sorry I should have given more details. The disks are formatted to EXT4 and they do appear to be read only. The attached details below are the results from /var/log/messages The first part is a disk that has files on it that I can read, but I cannot write to it. The second part is a new disk that I have recently formatted and has no data on it. Trying to mount this second disk previously I got a message about dbus, but I didn't this time. What I would like to do is to create directories and copy files into those directories to create a backup. David.
