I'm using Centos 4.3 / gnome

When I plug a usb flash disk as root, the drive is automounted and the icon shows up on the desktop (nice).

But with any other user when I plug any usb drive there's no icon on the desktop, and if i open computer, the icon is there but if i try to open it there's an error message saying that only root can mount that drive.

I've tried some things like editing the fstab but with no success.

what should i bee looking for here?

thank you,

Daniel
