EDIT: I found the problem, I think! I attatched my burner to the primary IDE channel (as Slave, with my HDD being Master) and it works! It burns at the correct speed and verifies perfectly! ^^
Well, it's not perfect, cause the I got a buffer underrun one one of my two burns, and in the other one the burn finished with only 14% Buffer remaining (probably cause data transfer rate between devices on the same IDE channel is pretty slow compared to if they're on different IDEs), but it works! Now I only got to figure out what the problem with my secondary IDE is...
Um... which one of the various burns? >__>
And, um, where can I check that chipset?
Here's one from today, with test write, then real write, then verify:
