[xubuntu-users] changing ownership on thumb drive

[JMZ]

Hi,

I'm having some weird issues with thumb drive ownership.  Steps:

1) 'sudo blkid' to call up the thumb drive assignment

2) 'sudo mount /dev/sd* /thumb' [where /dev/sd* is the drive assignment, 
and /thumb a directory off of the root]

---> 2a) [NB: /thumb is owned by the local account (here, 'blah') 
__before__ the mount command.  Afterwards, the mounted thumb drive is 
owned by 'root' and can't be changed]

3) 'sudo touch /thumb' [for some reason, I get the default DEC 31 1969 
when I mount the thumb drive]


but, when I type

'sudo chown -R blah:blah /thumb', [where 'blah' is the local account], I 
get

'chown: changing ownership of '/thumb': Operation not permitted'

***

The chown switches -R or --recursive do not work. [there are 
subdirectories on the thumb drive, and I would like all subdirectories 
to be changed to 'blah' ownership]

I suspect that the system's assignment of a wrong date/time to the drive 
might block the ownership change even after 'touch'.  Is 'touch' 
counterproductive?

I have disabled automounting of thumb drives or indeed anything not in 
fstab [ie. hard drive].  I have removed the /media directory.


Any ideas?  Thanks,
Jordan
