So I recently got a Benq DW1655 as a secondary drive to my Benq DW1650 which I've had for a while. Solidburn is enabled on both via Qsuite. On the DW1650 I had 1 bad burn where the DVD looked like it had a couple of shadows the size of raindrops on it. After doing a quality scan, the quality rating was 0.
On my new DW1655 2 of the first 4 burns were bad. (had those raindrop size shadows on them) All these burns were at 12x on Verbatim 16X R+ MCC04 from the same spindle. My DW1650 only had one bad burn with after using alot of Verbatims from other spindles. After reading a few of the threads at CDfreaks I switched to BCDB for my DW1655 and BCFC for my DW1650. I also turned off Solidburn for "known" media but the problem persists.
Here's some pics of my defects if you're interested. (dark shadow spots that can only be seen at certain angles close to the light; not really "rings") This is with Verbatim 16X MCC04 burned at 12X. Prior to burning, the physical media looks defect free under a lamp. The defects are occuring the the same area on each disc and have the same pattern. Eg. \ /
Any ideas what the culprit is and what causes these "shadows"? I'm using the same spindle and it seems that I get these defects more often on my DW1655 and not as much on my DW1650. It could be a bad spindle and I do have another spindle I could test.
