Re: 2.6.8.1 Mis-detect CRDW as CDROM

[Marc Ballarin <Ballarin.Marc@gmx.de>]

List of SCSI commands in cdrecord and k3b. Completeness and corectness are
not guaranteed and not even likely. Not all commands are actually used,
some are only for older hardware.

MODE_SELECT_* is not needed by cdrecord and fails gracefully as Kai
Makisara suspected. k3b seems broken, as it doesn't recognize devices as
writers if MODE_SELECT_10 fails (even when opening the device read-only).

Commands prepended by "->" are (probably) not mentioned in kernel include
files.

Now all that is left to do is determining which commands are safe and
fixing apps that only open devices read-only ;-)
