Your optical drive gets asked for 2 blocks iand answers that there is no medium recognized in the tray. The request was to read from block 0x07fffc = 524284 = 1023.9921875 MiB = 1 GiB - 4 KiB. This is not a usual medium capcity. So i wonder from where the caller had that block address. > kernel: [ 9.507731] sr 3:0:0:0: [sr0] tag#31 unaligned transfer I wonder what might have caused this. But this line brings me to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=948358 where pior...@gmail.com tried to get this processed as bug of udev. No solution was found. > kernel: [ 9.602797] sr 3:0:0:0: [sr0] tag#3 FAILED Result: hostbyte=DID_OK > driverbyte=DRIVER_SENSE cmd_age=0s > kernel: [ 9.608514] sr 3:0:0:0: [sr0] tag#3 Sense Key : Not Ready [current] > kernel: [ 9.614297] sr 3:0:0:0: [sr0] tag#3 Add.

More plausible as a wild guess, than 1 GiB - 4 KiB. What happens if you give the drive a readable DVD ? Maybe the software which issues the READ commands shows up with some more enlightening complaint. Have a nice day :) Thomas
