Mr Bitey Posted July 17, 2007 Posted July 17, 2007 (edited) Howdy All, My Pioneer 111L 8.29 has started having trouble burning discs and im unsure where the problem is. The drive has been working fine for ~6 months, flashed as a 111L 8.29 (Bufallo) with a mediacode speed edit to remove the ripping speed restriction (nothing else modified). The disc burns 'ok' in that there are no burn errors, verifies ok and shows a good quality score in nero cd dvd speed (in itself) and kprobe2 (on a liteon dvdrom). However during the burning process, the drive slows down the speeds up, then down/up (you'll see in the graph) in IMGBURN the device buffer remains ~94-100 and the ram buffer remains at 100%. The burner is on a secondary IDE controller (on the motherboard) and is the only drive connected (its a master) on a 80 wire cable. BIOS is set to Max UDMA, windows device manager says its using Ultra DMA (mode 4 from memory, ive also deleted all the IDE controllers and windows has redetected them to double-check). Ive reinstalled IMGBURN, gone back to default settings and tried changing from elbycdio to SPTI with no difference found (same problem). Ive used TYG03 and RITEKF1 media (same problem) - exmaples of both are below. I also see a similar problem using Nero Cd dvd speed (create disc) (graph included) Below is a Log, and link to the dvdinfopro graph and a nero graph. For the record, ive also tried dropping the burn speed to 8X - same issue is present. Any assistance would be greatly appreciated!!! before I start swapping drives or getting out the windows xp cd for a re-install. LOG: I 19:28:41 ImgBurn Version 2.3.2.0 started!

LIGHTNING UK! Posted July 17, 2007 Posted July 17, 2007 That's just the drive performing WOPC - 100% normal for Pioneer drives. There's really no need for the 256mb buffer (unless for testing purposes), it just takes RAM away from Windows. 40MB is fine.
