Re: kernel errors

Hi,

the log messages about "unaligned transfer" would be explained if indeed
the block size of the drive would be mistaken as 512 bytes rather than
2048 bytes.

So it might be interesting to let lsblk report "sector" sizes as perceived
by the kernel:

  lsblk -b -o VENDOR,MODEL,SIZE,PHY-SEC,LOG-SEC /dev/sr0

I get from the empty drive (last medium in was a CD-RW):

  VENDOR   MODEL                 SIZE PHY-SEC LOG-SEC
  HL-DT-ST BDDVDRW GGC-H20L 287483904    2048    2048

and with a BD-RE loaded:

  VENDOR   MODEL                   SIZE PHY-SEC LOG-SEC
  HL-DT-ST BDDVDRW GGC-H20L 24756879360    2048    2048


Have a nice day :)

Thomas
