Interestingly enough, I don't think powerec kicked in during any of the burns were it was enabled. I assumed this from reading the log in plextools pro and in nero (Which iirc mentions whether powerec was triggered during the burn). Feel free to correct me if I'm wrong in this.
I read through that thread, and I noticed that a lot of your burns are showing POF errors? (the brown spikes in plextools) Those ARE POF errors, correct? Is this because the 755 reads the discs back much faster during checking or do I not have something configured right here? I never got those spikes during scans, with good or bad PIE.
Well, for kicks, I burned a virgin RICOHJPN W21 ridata 8x DVD+RW disc and got this result burned at 6x. 8x on other (virgin) W21s started out looking like 6x burns until ~700MB, then the PIE skyrocketed up over 1000.
While not great, it seems above avg for an +RW. I noted that that 'hump' around 2GB is not present. Perhaps it's due to write speed? I also burned an MCC004 at 8x and it was a perfect burn (mostly sub 10PIE and no POF/files copy back@full speed), which is why I asked whether my drive was failing. It's a few years old, but I haven't burned THAT many discs with it. The best Qcheck TA test score I've gotten with any of the discs I've burned in the last week has been good-good-good. Most were worse than that.
The read tests were done on other computers I've got access to. I didn't do any analysis scans, I just copied the data to the hd while listening for drive 'distress.' One machine was a dell 600m laptop witha dvd/cdrw 'combo' drive (dvd-reader only). Another was an apple powerbook with dvd writer. They both had trouble reading back the discs. At the very least, they kicked down to slower speeds with lots of reseeking halfway through, and with some of the worst discs, the drives gave up entirely. The ultrabad burns had PIEs around 400-500 between 1.5 and 2.5GB. No POF. The discs that merely slowed the drives had scans close to the ones I linked to in my 1st post.
I guess I approached the burn quality test from the opposite point of view. If a burn can be read well by the majority of drives, then it's a good burn. if lots of drives have issues with it, it's perhaps not so good even if it burns/scans well on a known good writer and reader. Is this a bad assertion to make?
Anyway, I'll grab some +R yudens and see what I get. Which MID would you suggest for the 716? 02 or 03? If I have the same issues with these I've had with the others, what would you assume? I've been eying the 760a and possibly the pioneer 111 as possible replacements should it be the drive.
Thanks again for your help and feedback.
