Unfortunately, my luck with the 716SA has not changed. The new drive I have burns TYG02 8X DVD-R media (from the same batch) better than my old drive, but, other than that, it isn’t much of an improvement. Here is my latest scan (using firmware 1.07) of a TY 48X CD-R (Fuji branded). It is totally horrible. What is the problem here? Well, rather than revisiting the same question without any answers, I would like to suggest possible solutions. Unlike many people who visit this forum have a 716 drive, I have the SATA version. I am guessing that a SATA issue or some issue inside my system may causing my lowsy results.
I am going to try the self-test immediately. It will tell me if there is an issue with the drive, but I doubt that.
Switching SATA ports–I have the drive hooked up to SATA port 1 (second SATA port) with a WD Raptor on SATA port 0 (no RAID, using ATA mode). Could putting the drive on SATA port 2 or port 3 help?
Switching SATA cables–I used the Plextor supplied cable.
Could thermal issues cause the high C1 issue?
Since both my current drive and my last 716SA have the same problem with CD-R write quality with high quality TY media, I am guessing that it may not be the drive but something else causing the problem. The issue is not the media, as I have already had good results with this batch of media on other drives.
