Hello, I have the plextor 708A. I've had it for about a year and 2 months now. It was working fine, until I decided to update the firmware to 1.09, it worked, but when I did other hardware updates on my system, things went kookoo with the drive. I'll insert a blank dvd, or dvd with media, even movie dvds bought from the retailers, and it will light up light green, then go blank and into about 2 orange blinks, over and over.
I've switched the drive from slave to master, removed jumper to make it ultra dma, which also included me trying 3 different firmwares, 1.06, 1.09, and 1.10. No luck, and the drive reads cds without a problem, only issue is with dvds. The self test was tried around last month or so with plextor tech support, back when the rep almost was going to have me rma, but it worked after the 1.09 patch. So we didn't rma it, but at the time I was pushing my luck because he said the warranty was about to be void in a matter of days.
He said after that I'd be better off replacing it, then trying to get it repaired by Plextor. So here I am a month or so later, thinking I'm going to have to replace it, but I hope someone here might have some good solution.
