Thanx for the sites.. I read them and now I begin to understand a bit about permissions.
Well, the hd was mounted at /mnt/hdb1, so I didn't change that because I think it's useless. I'll put my files then under /mnt/hdb1. But of what do I have to change permissions. /dev/hdb1 or /mnt/hdb1. I can't see anything wron about the permissions
dieter@dieter:/mnt$ ls -l /dev/hdb
brw-rw-r-- 1 root disk 3, 64 Jun 9 2002 /dev/hdb
dieter@dieter:/mnt$ ls -l /dev/hdb1
brwxrwxr-x 1 root disk 3, 65 Jun 9 2002 /dev/hdb1
dieter@dieter:/mnt$ ls -l /mnt
drwxr--r-- 2 root root 4096 Jan 1 1970 hdb1/
