Just newly registered to this forum, so I was hoping someone could figure out what was going wrong.
Anyways, I have 2 Sony AW-G170A's (firmware 1.71) in my PC. I've burnt many things off of both drives in the past with no problems.
I then bought a 50 pack of Zero Defex 16x -R's. And I'd seen many posts on various forums saying they're crap, but I tested them out and they worked. So I burned 25 or so disks from that pack to free up space on a HDD. They all worked perfectly, I could even play them in my old IBM T21's DVD drive. That was several months ago, and I hadn't burned anything since. Nothing new has been installed on the PC except for updates and a couple of games, and no ad-ware of viruses on the PC.
I'm having a clear out on my hard drive again, so I can have a reformat and reinstall of windows, but now I can't use either of my DVD burners to burn onto those Zero Defex disks. Nero gives power calibration error's, alcohol 120% just sits there, spinning the drive for 10 mins, with the burn process at 0%.
I googled up the Nero errors, and found that the power calibration error can be a symptom of defective media. So I tried some Imation 16x +R's I had laying around and they worked fine. Tried some Zero Defex again, and no luck.
It strikes me as odd that I can burn 25 DVD's straight and have no problems, and then come back some months later and try to burn the last 25 and have them all turn out as coasters.
I was reading some of the other posts about AW-G170A problems, and someone suggested upgrading the firmware to Optiarc 1.04. Which I have now tried and no luck with the burn proccess on the first 3 disks.
I know the solution to this would be not to use cheap and crap media next time, but I still have another 50 pack of those Zero Defex disks which I doubt I can send back, and it would be a waste to not be able to use them.
I know my DVD burners can burn onto these disks, and I doubt it was just a coincidence that the first 25 I just happened to have burned were just good disks, and the rest just happened to be bad disks.
Anyone have any ideas?
