I note that the time stamp for the mounted directory is the same in both
your carex and test00 mounts. This would indicate that you have either
not umounted the partition or that the mount information has been cached.

The other issue however is that the permissions come from the files on
the device you've mounted. You can override this with special options in
the mount command in some cases.

Hi Carex,

There is a lot of cool information about your mounted drives in
/etc/mtab

cat /etc/mtab | grep -i sdb9

If you mount sdb9 manually it has to either be in fstab or
be mounted by root (or sudo). If you mount as root (not is fstab)
you have to use the gid and uid mount options (man mount) for the
user(s) to be able to use it.

HTH,
