Problems Setting L0 Data Zone

Ha I fixed it!  

This may work for other people with Lite-On dives that are having problems:

First I reflashed with the original KSOA firmware, then uninstalled under hardware manager then shutdown and disconnected the drive.  Then I took it apart and removed the controller boards and the metal drive apparatus.  From that I removed the spindle motor, then the servo motor.  Then two metal plates and a spring were removed and the slider bars came out and the lens was removed.

  1. I cleaned all the inside parts including the pcb boards and ribbon cables with a paper towel and rubbing alcohol (91%).  Then I swabbed the laser lens first with a q-tip soaked in alcohol, then very carefully scrubbed with alcohol soaked edge of folded paper towel.

  2. Next I saw two potentiometers on the lens assembly so I decided to tweak them.  Originally they read out to be .415K and .726K.  I dropped them each 100 ohms.  So they read about ~.303K and ~.615K instead.

  3.  I replaced the lens and slider bars and secured them into place, then attatched the servo motor.  Then I took a q-tip and soaked the tip in some olive oil.  I swabbed the slider bars and the servo rotor grooves for lubrication.

After tweaking the pots, cleaning, and lubing the drive, I put everything back together.  The ribbon cables were reattatched and the pcb boards were snapped back in place, the tray and cover were replaced.

Once the drive was all the way back together, I shut the computer back down and hooked the drive back up.  Then restarted and let windows reinstall the drive.  By the way, I had done this before taking the drive apart and it still didn't work.  However after doing the above:

Tried to burn a stealth extreme DVD file using image burn.  Set the L0 data zone then wrote each layer fine.  Then it closed track and finalized the CD no problem!  Put in xbox 360 VIOLA it booted!

So there ya have it.  Shows what a clean/tweaked lens can do!
