From http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=457386 :

"the fix for the load cycling error gets applied to optical drives as well
as hard disks. this leads to somewhat scary kernel log errors such as

  Dec 21 21:56:48 kernel: hdb: drive_cmd: status=0x51 { DriveReady
  SeekComplete Error }"

Problem:
hdparm -B 254 is applied to /dev/hdX and /dev/sdX.
Some of these may be optical drives which don't support setting power management levels.

Affected releases:
This probably does NOT affect Gutsy ( DVD-drive here on Gutsy is /dev/scd0 - can one rely that optical drives will be /dev/scdX ? ).
I don't know about older relases. (Dapper, Edgy, Feisty users: What is your DVD, CD-ROM drive called?)

Impact:
"scary kernel log errors". Nothing else for now.
