My DW1640/EW164B has been acting up lately. The TRTs look like this even on good discs. TRTs of a single layer disc look roughly like the first half of this one.
I tried the drive on two different controllers, used different cables, and checked the discs I was using by doing TRTs on my other 3 drives and they all looked fine (nice smooth upward curve) on the other ones.
The weird thing is, if I do a TRT or a quality scan of a CD on the BenQ, it works fine.
So, is the drive going south? Or is it something silly like "take it apart and clean the laser".
I could really use your help as this classic drive is an integral part of my collection and it's near impossible to find these days.
edit I should also mention that I am using this drive internally, despite its external firmware.
