I think this bug is specific of MyBook drives with ID 1058:1170 because I have two MyBook drives (one 1140, the other 1170) and only the 1170 one gives problems. That is, the 1170 is not automounted by the system, while the other MyBook drive, and all USB pendrives I have tested, work as expected.
Moreover, I've noticed that the 1170 gets listed by lsusb and blkid, but does not get listed inside /dev/disk/by-uuid/ and its partition is not listed in /dev/disk/by-id either.

Anyway, I can manually mount it (with sudo mount...) and it appears to work fine. udisks --mount /dev/sdd1 Mounted /org/freedesktop/UDisks/devices/sdd1 at /media/disk -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1263013 Title: External (USB) HDDs are not automounted in 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udisks/+bug/1263013/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
