i upgraded my 40125S to 48125w whithout problem. However, i tried it with another 40125S drive, but now, it opens and closes the tray SIX times before it recognices any disk.?Â¡'Â¡?Â¿?Â¿?Â¿?
I back to 40125S with no result. I tried several versions of both models, but I can’t get it works well.
Before this, the drive worked well.
