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.
1) 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.
2) 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?
3) Switching SATA cables--I used the Plextor supplied cable.
4) 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.
