Hi,
This mounts FFS, ext2fs, NTFS, MSDOS but not cd at the moment and falls
back to ro mode giving a message saying so on a single user X11 session
with places to add logging via logger.
You can put /etc/hotplug/attach-user in /etc/hotplug/attach and it
should work (if not strip out the sudo usage) or use the various files
to only run the mounting as root via sudo.
The one which runs via sudo requires attach, attach-user,
sudoers.include. Both should have logging and comments added but I
haven't the time right now but it should be easy enough to follow. Let
me know if you have any issues.
If you have problems with it inlined I'll attach them and send them
privately. Just let me know.
ntfs-3g is set to remove_hiberfile. If you dual boot you may want to
change that.

Perhaps it was unplugged without first being unmounted?
