I have had this problem with two DVD-R drives so far, so I’m pretty confident it isn’t the drive (NEC 2510A & Pioneer 108 v1.10 firmware). I’m using Taiyo Yuden media (and I’m just doing simulations anyway), so I’m pretty confident it isn’t the media.
P4 2.8HT system, 1gb ram, no unneccessary programs or services running.
The burner is the only devices on the IDE chain. Verified that the burner is running in DMA mode (UltraDMA mode 4). Doesn’t matter whether the bios is set to recognize the device as [Auto] or [CDROM].
Both Alcohol 120% and Nero are unable to keep the buffer full to maintain max write speed. They both start out by filling the buffer and starting the write at 8x on an 8x disc. The buffer slowly goes down… once it reaches 0%, the burn slows considerably (sometimes down to 1x). I’ve found that my “average” write speed across the whole burn is something like 3x.
Anyone have any ideas as to why my system/software can’t keep the buffer full? I’m using good 80 pin IDE cables, and I’ve tried swapping it out already.
