As they are > external disks for backup it should be fine. hmm... how can I "catch" which is the label of the attached disk? 'Cause (theorerically) udev gives disk id by disk phisycal attributes, eg serial... Label is _not_ a phisycal attribute (as I know). Is there any way? >> The disk-by-id symlinks has created correctly: >> # ls -l /dev/disk/by-id/usb* >> /dev/disk/by-id/usb-SAMSUNG_HD642JJ_31AF4D71B000 -> ../../sdb > ^^^^ > >> /dev/disk/by-id/usb-SAMSUNG_HD642JJ_31AF4D71B008 -> ../../sdc > ^^^^ > >> As you can see there are the correct serial numbers. As you can see I wrote that :) again: >> The disk-by-id symlinks has created correctly: > Yes, but they get a different ID: one disks lasts with "B000" and the > other with "B0008". Curious :-S hmmm... I think they didn't _get_ serial - they _have_ serial. and my problem is system can't recognize that. And it's more than curious... :P >> What could be the problem? > > Dunno, but you have many choices for designating the disks (label, id, > uuid and path). Choose your poison :-) do you mean I have to read the symlink of devie, and determine the phisycal disk by that? (but the question is still opened: why doesn't recognize the system the different serial numbers?) thank you: a. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
