I just got a new Toshiba SD-R1002 CD-RW/DVD drive and went to use cdrdao 1.1.5 on it, only to get this error message: > Executing power calibration... > ?: Input/output error. : scsi sendcmd: no error > CDB: 54 01 00 00 00 00 00 00 00 00 > status: 0x2 (CHECK CONDITION) > Sense Bytes: 70 00 05 00 00 00 00 0A 00 00 00 00 20 00 00 00 > Sense Key: 0x5 Illegal Request, Segment 0 > Sense Code: 0x20 Qual 0x00 (invalid command operation code) Fru 0x0 > Sense flags: Blk 0 (not valid) > cmd finished after 0.002s timeout 180s > Power calibration not supported. > Writing track 01 (mode MODE1/MODE1)... The rest of the write session went just fine, and I could read the CD-R in my CD-ROM drive. Still, should I be concerned? cdrecord 1.9 seems to be just fine and dandy with its power calibration: > Waiting for reader process to fill input buffer ... input buffer ready. > Performing OPC... > Starting new track at sector: 0 Is this a bug with cdrdao? -- It has been justly observed by sages of all lands that although a man may be most happily married and continue in that state with the utmost contentment, it does not necessarily follow that he has therefore been struck stone-blind. -- H.

No, it's just fine. The explicit power calibration command is an optional command in the SCSI-3/mmc specification. I guess cdrecord just does not report any error if it is not supported. And I should do the same for cdrdao. Usually the drive performs a power calibration automatically when the write process is started so you do not have to be worried at all.
