So....after multiple tests there was no margin for improvements. It's been two hours, i rotated the knob a little clockwise....counterclockwise......a bit less.....a bit more.....nothing!! CD Speed 99 keeps failing at at all test.......the noisy laser head keep smashing forward and backwards in the rails as shown in the video
I assume there is no hope, right ?
What your laser head was doing is tracking, it couldn't locate the track successfully. As an end user what we can do is pretty limited. In a standalone CD/DVD player, there are more pots you can adjust, the focus gain/tracking gain/ef balance, most of which doesn't exist in a disc drive for computer use like yours. As for tuning the pots, it gets a little tricky sometimes, as a small amount of adjustment makes a huge difference. See this video for reference. This guy does it very well.

i'm testing another Pioneer ( the DVD-105SZ ) which is basically the same model. It read CD-R flawlessy, but struggle....with DVDs and CD-RWs.
CD Speed 99 fails on "random seek" test. My patience is running out....
DO test the drive with commercial discs, as those recordable discs are difficult to read for older drives. Especially for CD-RWs, they are way more difficult to read even than CD-Rs. And you have to keep in mind, don't over do it, or you'll end up..... See the picture.
