Message #27 talks about a fix. Should it be already available on kernel 2.6.31-15 ? I tried again to connect my disk after the last kernel update but situation is always the same, /dev/sdbX is not created and the messages: [335430.696114] sd 2:0:0:0: [sdb] Sense Key : No Sense [current] [335430.696126] sd 2:0:0:0: [sdb] Add.
