I have a 1640 and a 1670 on the secondary IDE channel. The 1640 is master, and the 1670 is slave. Recently, when burning or even just reading DVD’s or CD’s in the 1640, the PC shuts down. Reading or burning in the 1670 is fine.
Device manager shows the 1640 is set to UDMA-2 and the 1670 is set at UDMA-4. Board is a Chaintech VNF3-250, IDE driver is the 5.10 nForce drivers. I uninstalled and reinstalled the nForce IDE driver, and the drives are still picked up as UDMA2 and UDMA4.
First, I didn’t think the 1670 was UDMA4 capable, I thought it was a UDMA2 drive (as I thought pretty much all opticals were). I’ve included a pic, just to prove I’m not crazy.
I’m fairly certain that the shutdown issue is related to the different DMA modes. Any thoughts as to what the issue could be or what’s causing the problem? I doubt that it’s software, since it occurs whether I’m burning with Nero, IMGBurn, Decrypter, or even when I’m just reading the disc. It’s not overheating, since even encoding and burning with NeroVision doesn’t kick the temp above 50C (of course, only on the 1670, since the 1640 results in an immediate shutdown…and I mean immediate—as soon as the disc spins up…BAM!) I even tried different firmwares just in case.
