I got my 111D a few days ago, and have been testing it before crossflashing to Buffalo firmware. In my testing, I’ve come across a bit of a problem. When burning media at 8X like YUDEN000T02 and MKM001, it seems to start off at 6X for the first minute and a half, then almost like it’s switching gears… will start to slow down, almost to 0, then shoots up to 8X. I tried the same thing for YUDEN000T02 @ 12X, and it’s even weirder. It does this twice. 6X for the first minute and a half, then shoots up to 8X for the next few minutes, then shoots up to 12X for the rest of the burn. I tried ProdiscF02 and it gave similar results @ 12X. To answer some hardware questions before they get asked, I’m using my Pio as secondary master, with my BenQ DW1640 as slave. Pio is running in UDMA mode 4 using an 80 wire cable. Also, at no point did the buffer levels indicate an underrun or dip significantly. Software used was Imgburn 220.127.116.11 in write mode.
Is this a firmware problem, a hardware problem, or is this normal?
I’ve posted a quality scan and a TFT for the YUDEN000T02 burned at 12X.
