Ok, here’s the back-story.
I have a Plextor 716A that was working just fine in May of 2005 When I bought it.
Around June or July it started burning with data verification errors in Nero.
I contacted Plextor, and they replaced my drive.
The problem seemed to go away, but now it’s back.
I have an Asus Motherboard with an Nforce 2 chipset, (without the Asus IDE drivers installed)
I just updated my Motherboard Bios, Drivers (all but IDE), and Drive Firmware.
I don’t think the problem is Media related (but I’m no expert).
Here’s a couple of typical scans.
Keep in mind that both of these scans are from discs that are BAD (failed data verification) I can confirm that the data verification is working correctly, because I have seperately verified this via MD5 Sums of burned files.
