Without a DVD in the drive /dev/sdb goes. Even with a disc in the drive, however, in CD Player for example the box in preferences to select the device is greyed out. Sound juicer "... could not find any CD-ROM drives to read.". Totem has eject and play/pause greyed out when a DVD is in the drive and the open dialogue has no option to point to /dev/sdb. -- Regards Simon
