This SCSI command needs support inside the drive... |
| 41 |
|
| 42 |
It will not work for DVD media and some drives do not support it even for CDs. |
| 43 |
|
| 44 |
Also note that there is still an unfixed problem on Linux that under unknown |
| 45 |
conditions modifies the SCSI commands before they are send to the drive. |
| 46 |
As long as Linux does not allow to retrieve at least the 18 standard bytes |
| 47 |
of sense data there is no chance to find this problem as the drive writes the |
| 48 |
information about the location of the unwanted bits into the last 2 bytes |
| 49 |
that cannot be retrieved on Linux..... |
