Potential disaster for Rev/Linux pendrive apps

This reminded me of something on OS X: If you do a 'Get Info' on an  
attached storage device there is the option (tick box) to ignore the  
ownership permissions on the device. There may be a general setting  
for attached storage devices in Ubuntu, or similar option on one of  
the property tabs once the device is attached.
Gnome has been enhanced with added management features, so this may  
be one of them.
Might need to look see if plugdev has group membership.

Can you get it to work as root?

In fstab, is it mounted with 'auto' or does it display the correct  
filesystem type?

Does it work in 6.0.6 LTS? I've had some issues with 6.10 and USB...

Cheers,

Luis.
