(Sense Key Code)
|--------+--------------------------------------------------------------------|
| 5h | ILLEGAL REQUEST. Indicates that there was an illegal parameter in|
| | the command descriptor block or in the additional parameters |
| | supplied as data for some commands (FORMAT UNIT, SEARCH DATA, |
| | etc.). If the target detects an invalid parameter in the command |
| | descriptor block, then it shall terminate the command without |
| | altering the medium. If the target detects an invalid parameter |
| | in the additional parameters supplied as data, then the target may|
| | have already altered the medium. This sense key may also indicate|
| | that an invalid IDENTIFY message was received (6.6.7). |

mein problem:<br>
ich kann mit der fehlernummer nix anfangen.<br>
ich hab versucht mittels aspi von eine audio-cd daten zu lesen...<br>
<br>
kann mir da bitte einer helfen?<br>
