[newbie] Disk icons.

[Goldenpi]

I have been messing with drives, adding more hd's and a seconds floppy
drive. I created the link from /mnt/some_drive to a file on my desktop, but
had to log in as root to set the icon. Then I found the icon in /mnt had
changed as well. An hour of investigating revealed that the icons on the
desktop arn't links, so what are they and how do I create them.
