None of the Dataxx partitions are displayed in running
cat /etc/fstab as me (user) - the Dataxx partitions are mounted by
selecting them using the Places -> Removable media facility.

Data01 to Data04 are readable and writable, being mounted this way.

I do not remember whether I had rebooted after running the chmod
commands on the two partitions, but, as the system crashed/froze while
I was trying to reload firefox before rebooting (to try to avoid
losing the last session, as mozilla abolished the Save session
functionality), I have now rebooted, after running the chmod 660
command as advised on both partitions, and they are sill not writable.
