USB device permissions... again

[Gabriel Dragffy]

I have an external hard drive formatted with FAT32, when connected (and
a user belonging to the plugdev group is logged in) then it get's
auto-mounted and gets the permissions 700 for whoever plugged it in.

Is there a simple way of adjusting what permissions this particular
device gets mounted with?

Furthermore I decided I wanted to change the format to ReiserFS, I wiped
all paritions and created a single one and formatted it with Reiser 3.
When mounted this device could only be accessed by root, even though
other users were in the plugdev group. I reformatted and recreated the
partitions and no change. It seems like a completely pointless system of
mounting it so only root can access it. What's the deal?
A way to change that behaviour would also be appreciated.

I don't want to end up adjusting the permissions universally for all USB
sotrage devices, just that particular disc and going the fstab rout just
doesn't cut it.

For information, I'm dealing with a Lacie 80GB portable external hard
drive (USB2).

Thank in advance if someone can help me out.
