Basically, just as with any ext3 partitition, you can only write to directories that the user you're logged into is allowed to. /media/disk for my external drive when mounted is mounted as: drwxrwxr-x 5 root users 4096 2007-04-22 22:14 disk Bsically, just treat it as you would any other ext3 partition.
