No, I mean the HD LED is red all the time, even during normal CD/DVD reads in the NEC drive. My NEC drive LED is green during burning and reading.
Its even doing this with my Plextor 40x CD Writer now too and it didn't before I installed the NEC yesterday.
My PC also slows down considerably during a CD or DVD burn and quite a few buffer underruns occur, the hard drive seems to be accessed like crazy. I'm burning from a image file (ISO), not 1:1 DVD copy.
My basic PC Specs:
AMD Athlon XP2000+
512MB DDR333 2700 RAM
Secondary IDE Master: NEC 2500A DVD Writer.
Secondary IDE Slave: Plextor PX-4012A CD Writer.
