Looks like your UUID is 359f5eea-47cb-42c4- > b96e-974b6f07ad19.

Hi, Continuing on with this, I have the following entries in the directories in /dev/disk (sorry for the mangling): $ ls -l */ by-id/: total 0 lrwxrwxrwx. 1 root root 9 Nov 23 18:04 ata-HITACHI_HTS541612J9SA00_SB3D41EWGSZ5RL -> ../../sda lrwxrwxrwx. 1 root root 10 Nov 23 18:04 ata-HITACHI_HTS541612J9SA00_SB3D41EWGSZ5RL-part1 -> ../../sda1 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 ata-HITACHI_HTS541612J9SA00_SB3D41EWGSZ5RL-part2 -> ../../sda2 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 ata-HITACHI_HTS541612J9SA00_SB3D41EWGSZ5RL-part3 -> ../../sda3 lrwxrwxrwx. 1 root root 10 Nov 23 18:04 ata-HITACHI_HTS541612J9SA00_SB3D41EWGSZ5RL-part4 -> ../../sda4 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 ata-HITACHI_HTS541612J9SA00_SB3D41EWGSZ5RL-part5 -> ../../sda5 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 ata-HITACHI_HTS541612J9SA00_SB3D41EWGSZ5RL-part6 -> ../../sda6 lrwxrwxrwx. 1 root root 9 Nov 22 12:06 ata-MATSHITADVD-RAM_UJ-852_HC43_043146 -> ../../sr0 lrwxrwxrwx. 1 root root 9 Nov 23 18:04 usb-ARNOVA_10_11223344-0:0 -> ../../sdb lrwxrwxrwx. 1 root root 9 Nov 23 18:04 usb-ARNOVA_10_11223344-0:1 -> ../../sdc lrwxrwxrwx. 1 root root 9 Nov 23 18:04 wwn-0x5000cca54dcae5d8 -> ../../sda lrwxrwxrwx. 1 root root 10 Nov 23 18:04 wwn-0x5000cca54dcae5d8-part1 -> ../../sda1 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 wwn-0x5000cca54dcae5d8-part2 -> ../../sda2 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 wwn-0x5000cca54dcae5d8-part3 -> ../../sda3 lrwxrwxrwx. 1 root root 10 Nov 23 18:04 wwn-0x5000cca54dcae5d8-part4 -> ../../sda4 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 wwn-0x5000cca54dcae5d8-part5 -> ../../sda5 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 wwn-0x5000cca54dcae5d8-part6 -> ../../sda6 by-label/: total 0 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 _Fedora-17-x86_6 -> ../../sda2 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 \x2fusr\x2flocal1 -> ../../sda5 by-path/: total 0 lrwxrwxrwx. 1 root root 9 Nov 23 18:04 pci-0000:00:1a.7-usb-0:3:1.0-scsi-0:0:0:0 -> ../../sdb lrwxrwxrwx. 1 root root 9 Nov 23 18:04 pci-0000:00:1a.7-usb-0:3:1.0-scsi-0:0:0:1 -> ../../sdc by-uuid/: total 0 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 359f5eea-47cb-42c4-b96e-974b6f07ad19 -> ../../sda3 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 d0b7bacc-879a-4b34-9ddd-76f438a28c5d -> ../../sda6 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 e082b796-2fc7-449b-95d8-a39ef6a29891 -> ../../sda2 lrwxrwxrwx. 1 root root 10 Nov 23 18:04 EEE4584BE4581863 -> ../../sda1 lrwxrwxrwx. 1 root root 10 Nov 22 12:06 f2ed8f21-da63-4def-a674-afdc90e448c5 -> ../../sda5 The two interfaces of the USB are in the by-path. From your e-mail, I understood that I may have to create an entry in the by-uuid? What should I use there then? Something else? Sorry that I am unclear here. So, I mimicked what was going on with another test case (USB) and tried the following: cd /dev/disk/by-path sudo touch ../../sdb1 (this command I think is not correct) sudo ln -s ../../sdb1 pci-0000:00:1a.7-usb-0:3:1.0-scsi-0:0:0:0-part1 cd /dev/disk/by-id sudo ln -s ../../sdb1 usb-ARNOVA_10_11223344-0:0-part1 cd by-uuid/ sudo ln -s ../../sdb1 ARNOVA\ 10 sudo mount /dev/sdb1 /mnt/myusb mount: /dev/sdb1 is not a block device (maybe try `-o loop'?) I suspect the problem is in the first stage (second command above) because the commands above don't know that ../../sdb1 is part of /dev/sdb. $ ll /dev/sdb brw-rw----. 1 root disk 8, 16 Nov 23 18:31 /dev/sdb sudo chown root.disk /dev/sdb1 ll /dev/sdb1 -rw-r--r--. 1 root disk 0 Nov 23 18:35 /dev/sdb1 How do I tell it that it is a partition, perhaps 8, 17 where the 0 is? (Sorry for the naivette? Will parted help here?)
