When setting up a volume or favorite, the device would best be displayed by the drive's uuid or id, rather than generic drive name. The drive name "/dev/sda2" can change after a BIOS upgrade or re-plugging a device, or even accidentally booting with a flash drive that was not removed during shutdown, which produces an error. This problem shows itself often if a favorite is set to automount. Most Linux distributions now mount disks by their uuid or id to avoid such problems. Rather than "/dev/sd??" it could be "/dev/disk/by-uuid/???????" Even /dev/disk/by-id would help to eliminate the problem.
