this is my first post here. I have the following problem with my CD+RW/DVD+RW combo drive SONY DW-P50A. Recently I was playing around reading a write protected CD that I was able to copy with no problem with CloneCD. This time I used ‘readcd’ in Linux which is a wrapper practically of ‘cdrecord’ for all of those that know.
Anyway, after reading the raw image of the CD and the bad sectors associated with it I tried to burn it but couldn’t. That’s when I discovered that the burning process became messed up! I started getting those “power calibration error” messages that hint to some de-calibration of the laser I guess.
I’ve tried to burn anything into any kind of media after that with no success. I can’t even blank any CD+RW anymore.
Now I want to stress the fact that this is not a media related issue, since I’ve used different kinds of media just to check with the problem and in particular the kind of media that I have been using for CD+RW didn’t give me any problems at all in the past.
The drive is able to read anything just fine (even from the CD+RW media that I can’t blank or burn) but it can’t blank or burn on anything anymore.
I went to the Compaq site and downloaded the firmware update for the specific drive that I had done some time in the past, thinking that it might reset the drive to a proper state but it didn’t do it. The problem persists.
So my hope now is turned to the knowlegeable people in this forum. Any good ideas on how to solve the problem? I know that there has to be something there that I can do to restore the burning function on the drive!
Thanks in advance!
