O.S. SuseLinux 10.0
GNOME platform
root name: Lebanus
I have an external HD partition as follows:
/dev/sdb4 /media/usbdisk 98.7 Go Linux native

Permission to write on the HD is denied as I'm not the owner.

I tried in superuser to change the owner as follows:
chown Lebanus /media/usbdisk_4
error message: you don't have the permission to change the owner.

Question: How can I get rw access to usbdis_4
