Hello
Sorry if it's not the right place :-)
I'm trying to execute a SCAN command on a Plextor 40TSi.
CDB is this:
scanBuff[OFF]=SCAN;
if (direction== (-1))
scanBuff[OFF+1]=0x10;
else
scanBuff[OFF+1]=0;
scanBuff[OFF+2]=0;
scanBuff[OFF+3]=startM;
scanBuff[OFF+4]=startS;
scanBuff[OFF+5]=startF;
scanBuff[OFF+6]=0;
scanBuff[OFF+7]=0;
scanBuff[OFF+8]=0;
scanBuff[OFF+9]=0x40;
scanBuff[OFF+10]=0;
scanBuff[OFF+11]=0;
Command fails no matter the parameters:
Check Condition
Host_status=0x00(DID_OK) Driver_status=0x28 (DRIVER_SENSE,SUGGEST_ABORT)
[valid=0] Info fld=0x0, Current SCSI command sense: sense key: Illegal
Request
Additional sense indicates: Invalid command operation code
Raw sense data (in hex):
70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00
Cmd handling is done by a handle_SCSI_cmd() similar to the one described
in SCSI prog HOWTO and works well. Exactly THE SAME command works on a
Teac CD-R58s. It seems to me that Plextor does not support this command,
but how is it possible? How can I implement a SCAN function?
I hope I've done a mistake somewhere...
