This SCSI command needs support inside the drive...
It will not work for DVD media and some drives do not support it even for CDs.
Also note that there is still an unfixed problem on Linux that under unknown
conditions modifies the SCSI commands before they are send to the drive.
As long as Linux does not allow to retrieve at least the 18 standard bytes
of sense data there is no chance to find this problem as the drive writes the
information about the location of the unwanted bits into the last 2 bytes
that cannot be retrieved on Linux.....
