I bought a BenQ DW1655 OEM with BCAB firmware. I burned several -R and +R media successfully at 4x, including 3 YUDEN000T02. The Nero quality scans looked fine on every disc, except on the 3rd YUDEN burn there was a small PIF mountain near the end. Every subsequent YUDEN disc I tried to burn with Nero has failed at some random point. During the burning I could hear the drive changing speed a lot. I even tried moving the drive to a different computer, used a different version of Nero, erased learned media with QSuite, etc. with no success. I returned the drive as defective after wasting many precious YUDEN discs. (Other types of media still worked OK.)
Another interesting thing I noticed is the burned surface on failed YUDEN media had very strange patterns in them instead of the usual even/smooth burned surface. It almost looked like smears in the burn.
I then got a different DW1655 (I/O Magic drive) which I crossflashed to BCDB firmware. Imagine my utter shock when the exact same scenario repeated itself on my YUDEN000T02 discs! The only difference is I got about 6 successful YUDEN burns at 4x. I can’t imagine 2 drives could be defective in the same way.
Does anyone know what this problem is that has bitten me twice?
I have the drive set to its defaults (WOPC on, SolidBurn on). Could WOPC explain this problem? I know the drive is supposed to learn and adjust its burn strategy, but I never thought it would go from near perfect burns to only bad burns. I haven’t burned enough other types of media to see if this happens on other media types. Right now it seems to be YUDEN000T02 specific.
Is burning YUDEN000T02 media at 4x not recommended on the DW1655? I’ll try burning at faster speeds, but it bothers me that media that once burned fine at 4x no longer can. I have less than a week to return this drive to the store if it’s defective.
