I’ve got a PX-716A, DLA 0304. It came with firmware version 1.04 and has worked very well in my Dell computer with a Dell motherboard, P4 3.6 GHz, Intel 925XE chipset. However, if I flash the firmware to version 1.04u (the latest), the drive will not burn CDs. When I use Nero 6, the program shows that the drive’s buffer receives no data and my computer completely crashes so that it needs a hard reset.
I have flashed back to 1.04 and the problem disappears. I have also confirmed this problem on another 716A DLA 0203. I’ve also tried this with both Cable Select and with setting the drive’s jumper to master. It’s definitely related to the new firmware. Plextor said that the new firmware addressed data corruption on certain ASUS motherboards. I wonder whether they introduced new problems with other brands of motherboards. I’m concerned that the upcoming version 1.05 may carry over this problem.
I know that many (maybe even most) of you have not experienced any problems with version 1.04u, but I’ve seen posts by others who have had problems. Luckily, I’m able to reflash back to 1.04 and not end up with a paper weight.
