Hello everyone. I found this site by searching Plextor's site for solutions to the problems I am having.
Up till a few months ago everything was fine. Then one day my Plextor PX-716A drive died. Hardware failure. It stopped reading/writing to disks. So I went out and bought 2 new Plextor PX-716A drives because I really like Plextor burners. Each of the drives had older firmware on them (1.04 if memory serves) so I got the updated firmware and tried to update the drives. I kept getting failed firmware error messages.
When I went to plextor's site they had a list of "things to try" to help with this issue. The 2 articles I reviewed and applied were...

I followed the directions in this post running the applications they suggested. It said I had no ASPI layer present so I ran the utility to install it. Then I reran the checker and it said my ASPI layer was installed and working fine but I still got the firmware update error message telling me the update attempt failed (telling me that this was not the cause of my failed firmware attempt). I then reviewed the second article...

This article told me to disable the DMA channels for both the primary and secondary IDE Controllers which I did and then I attempted to update the firmware and whallah, it worked. I then re-enabled the DMA for both controllers and since then every time I burn a CD or a DVD (I have wasted 2 +DL DVD discs now and 6 CD-Rs) the data is corrupted.
I have used different programs attempting to burn. A120%,
Nero, Windows default, Roxio. Each with the same issue. If I put in an already burned disc (game disc, previously burned disc I did) it reads it just fine. The issue seems to be isolated to burning, ALL burning.
I am not new to computers but I am not real up to speed on the whole ASPI layer but I am not sure I needed it and think it might be related to my problem since before I installed it I had no corrupted burns but cannot say for sure. I get corrupt burns on both of the Plextor PX-716A drives. The whole burn process seems to go flawlessly and when you read the burned disc the contents all "appears" to be what I burned but everything on it has checksum errors or corrupted in some way.
Any ideas or suggestions would be greatly appreciated!
