I was using A7V motherboard, but now got a new A7V133 with the latest BIOS, and I used 80pin cables to connect my Plextor 16x and DVD (2 cables, CD-RW is Primary Master and DVD is Slavery Master). I used 40pin cables before and it seems it gave better speed! my plextor copies 250Mb in 3 minutes! and it should copy approximately 600Mb in 2 minutes!! Intallations seem to be way longer...what to do? go back to 40pin cable? I wonder why...
Thank, You, for help

Then use a 40 wire cable. What's the problem?

if you ahve a problem, seperate the ata33, dma drvices on the slow 40 wire cable and the ata66/100 on the 80 wire one.

i personally have 4 devices

primary master: ata100 HDD
primary slave: ata33 HDD
secondary master: ata66 dvd
secondary slave: dma burner

all running on 80 wire cable and dont see any slowdowns or conflicts.

o yeah... help for u...

check your bios, make sure that the drives are still being detected as what they are
udma 5 = ata100
udma 4 = ata66
udma 2 = ata33
dma = ata (16mb/sec)

also check in your system configuration that DMA is enabled on all relivant drives.

if that doesnt work, you may want to consider running the drive by itself on a cable
