I have an AD-7173A, and I get this error whenever I try to burn a DVD.
The problems started after a few hardware changes (new main board, new PSU, new HDD).
Here’s what I tried:
- AFAICT I use good media (MCC 03RG20 – correct me if I’m wrong). This media has worked for me before with this drive.
- The drive shared its PSU cable with an HDD. I managed to temporarily get a cable for the burner alone. This worked once, by the way (doing this required disconnecting 2 out of 3 of my HDDs so I had to restore the old condition after burning. Next time I tried to do the same changes, the power calibration errors didn’t go away)…
- switching connectors, and moving the drive from slave to master (jumpered accordingly).
- upgrading firmware to unmodified 1-03 (was 1-01).
…and I’m out of ideas.
Thanks in advance for any help…
