With ext3 on the USB HD you end up having to treat it just like a “static HD”, i.e. you have to make sure that the permissions on the directory allows your user to write. In short, use chmod or chown :-) VFAT doesn't have permissions in the Unix sense (in any sense really). instead the permissions are set disk-wide at mount time. You can influence that through 'mount' options; -o uid=<user>,gid=<group>. See the “fat” portion of mount(8) for more details. /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus．therning＠gmail．com http://therning.org/magnus What if I don't want to obey the laws?
