UPDATE: (solved- sort of} See my answer below
I have 2 identical USB drives which I've both formatted to identical specs using Gparted. Both have two identical primary partitions (ext4 and ntfs).
I have not created any mount-point directories for them.
(An afterthougt: actually I did, but deleted them, so there are none now. and I did manually mount them (as a test)... Maybe(?) this has done something(?) but there are now no "created-by-me" directories in /media, for these USB drives)
There is no mention of them in /etc/fstab.
I want them to auto-mount, and I'd expect them to mount identically...
...but for some reason, the ext4 partitions are mounting with different permissions and different group.
As can be expected with root:root ownership, and no write permission for group/other, it is causing my rsync backup to fail (for usb2).
What might be causing these different mount settings?... (I'm using 10.04)
