I recently just purchased a NEC 3520a from newegg.com I was using a Pioneer DVR-105 and was able to burn cds and dvds with no problem. After the swap I was unable to burn anything to the NEC with Nero. Changed the drive to be primary master, single drive on the channel, and still no luck. Reinstalled XP SP2, and VIA 4-in-1, same problem. Nero goes to burn, caches the files and then locks. Can't even kill the process nero.exe. Infuriated I installed linux and was able to burn two different types of dvds with no problem.
I thought maybe nero wasn't liking that I hadn't set a region code on the drive yet. That didn't fix anything. Something weird I did notice though, All of my Hard disks and the nec drive are showing up as SCSI disks in the windows device manager. Read a couple of different online posts and saw that this was "acceptable". And after trying to upgrade the Via atapi Bus master driver, and not being able to boot I figure the installed driver was the correct one. Also I'm unable to use CDeX or iTunes to rip audio cd's (from the nec drive or a liteon dvd reader), but Windows Media Player 10 is able to play and rip the files.
Thinking that not being able to burn might be wacky firmware I decided to upgrade it to Liggy and Dee 1.U6. Under windows it said unable to flash and then the drive would blink green continuously until I rebooted. Under linux using necflash -scan it was unable to find a device, and trying to flash the device node anyway said it was unable to flash. Booted from a WinPE disk and tried to flash, it got farther than in regular windows, but after sending the checksum, it just errored out on every block it tried to flash.
Any ideas/suggestions on how to fix any of this?
