I have a (yes, crappy) 1.4 Athlon-based system, XP Pro, 256 RAM, with onboard ATA100 controller and one 100 and one 133 drive. My problem is, I cannot safely reach maximum speed for burning as my transfer speed to both my CD burner as well as my DVD writer never reaches above a certain point (about 41/42x for my CD writer and about 4.2 or so for my DVD writer.)
Now, from everything I've read, I should be able to more than safely write at max speed (52x for CD, 8x for my DVD burner), and yet I cannot. Well, more accurately, I can, but it doesn't improve performance as it's basically a game of buffer catch-up. (As well as with CDs, it makes discs that are nearly-impossible to read with all the link jitters)
DMA appears to be on (although I've heard that sometimes with XP it doesn't necessarily work when it's turned on), and it would seem (according to hard drive speed tests) that I can do many times the transfer rate needed to burn at max speed, and yet the Nero "detect max speed" option still reports the low results I mentioned.
Anybody know what the problem might be?
P.S. Oh yes, my DVD burner is the master on the primary IDE channel, and my CD burner is the slave on my secondary.
