Also I also checked the permissions on USB stick on the partition
which I want to export.



 ls -l
total 26
drwxrwxrwx 2 tapas tapas  2048 2010-02-12 04:12 HPLAUNCHER
drwx------ 7 tapas tapas  4096 1970-01-01 05:30 vol1
drwx------ 1 tapas tapas 20480 2011-01-03 17:43 vol2

I have not mounted them as above.When ever I connect the USB it
automatically is getting mounted as above on my laptop.As root I try
on vol2 of above

chown 755 /media/vol2
but when I now check the permissions there is no change.
when I do ls -l I get
drwx------ 1 tapas tapas 20480 2011-01-03 17:43 vol2
same thing.
How is this that chown is not working even as root?
Can this be the cause of the error we are having?
