Liteon 1693s Power Calibration Error

Hi all,

I have been using my Liteon DVD Burner for a good few months now with no problems, but lately some discs have not been read properly, mainly during O/S installations. Figured this might be because they getting used so much on my test lab

Bought some good and reliable media to do up a new batch, and now Nero log is showing a power calibration error, and every write fails

Tried the media on another machine, also with nero, and works well

Is my drive therefore cooked? No noticeable extra or different noises when trying to write discs (unsuccessfully)

If someone could cast their eye over the log then that would be great then

Hi gmilano and welcome to cdfreaks,

I found this on the Nero website:

[B]I get a ‘Power calibration error’ or ‘Calibration area (almost) full’ error message. Why?[/B]

Power Calibration is controlled by the recorder.

Before any write operation, all recorders must do a 15 step power test to determine the optimum power for writing to the CD; this is called “Optimum Power Calibration”(OPC). During the write, it continues to do this test to get the best write throughout the whole CD; this is called “Running Optimum Power Calibration” (ROPC).
This whole process is controlled by the recorder, though initiated by programs such as Nero. There is an area on the inner part of the CD for the test and test data info to be stored. You can use this area up to 999 times.

If you receive the “Power calibration error” or “Power calibration area is (amost) full” error message, the cause will be either poor media, poor power, or a defective recorder.

Please try the following solutions:

  • Update the firmware of your recorder. Please check the manufacturer’s website for the latest version.
  • Try another brand of CD-R or CD-RW media.
  • Try different power connectors, and for recorders, do not share power with other devices.
    It needs its own power connector. If the error occurs with an external recorder, the power source in the chassis could be the cause.
    As a test, try to take the recorder out of the external chassis and connect it internal.
  • Try different configurations, such as taking the CD-ROM to the primary IDE bus as slave and have only the recorder connected to the secondary IDE bus as master.
  • Send the recorder in for service.

Take care


Thanks for the welcome and the reply

No firmware shows up for my model on liteon official website having searched it, but I am sure there i saw some on this site. I was loathe to have to do that, not lazy but it looked very confusing

Look forward to my second post - How to upgrade firmware :slight_smile:

Not really - I’m sure there is a sticky somewhere

Your advice indicates possible bad media which I knew could produce this error message, but the media is ok in other recorders. The power issue on my computer seems not to be the case either as it has not changed or been damged since I could use the recorder previously

Therefore, looks like a bad writer :frowning:

Thanks again

i happen to have the exact same dvdrw drive tell me do you still have it and does it work yet and if so tell how you got it to work

The last post by [B]gmilano [/B]was posted on 18-07-2006, so I believe he lost interest in this subject, [B]seeker010[/B]. :wink:

Hi, I also have two liteon 1693s.I have not had any problems yet with them. But how ever I did not use nero. The only programs that I use is AnyDVD CloneCd and CloneDvd2. :disagree:

:doh: browsing cdfreaks through remote vlc to home is like drinking 12 cans of beer. I swear. :bigsmile:

I had the same problem with my 1693s trying to burn an iso using dvd decryptor and Nero with Verbatim media mfg code MCC 03RG20. I had previously used omnipatcher to modify the firmware KS0B to allow for lower burn speeds (ps2-related) for both the verbatim and ritekF1 media. The Ritek burns at 2x no problem, but the verbatim media throws the error. Tried connecting the drive to its own power rail and everything but it still throws the error. Ironically, the ps2 stutters when reading the ritek media, while the verbatim, burned at 2x on some generic laptop burner gets read flawlessly. Both media burn without problems at 6x or greater but high speed burns are impossible to be read by my ps2. Anyone have a low-speed good write strategy for Verbatim MCC 03RG20?

Still that useless myth about low speeds…

Use ImgBurn!!!

well, reflashed the drive back to the unaltered KS0B firmware, and using imgburn this time. I’m following the guide found here:

The lowest supported speed is 6x, so I’m going with that. Burned iso without any more power calibration errors and did a nero dvdspeed quality check. Results were PI error averages in the mid-100s, compared to the one burned at 2x, which is holding at ~15. The 6x burned one also won’t boot with the ps2. Obviously, there is some sort of quality issue happening here at high speeds, and Verbatim media is supposed to be in the mid-upper quality range. What needs to be changed to get a better burn quality?
