I just got a Sony DW-D26A from newegg and have installed it fine. I bought the new drive because my old dvd-rw was burning slow and my used read buffer was going from 100% down to very low, like 5% then back up, making for a long burn process. The new drive didn’t solve this problem. So I searched the forums and found out how to change me DMA.
My primary IDE Channel =
Device 0 Transfer mode= DMA if available. Current= “Ultra DMA Mode 5” Device 1= Transfer mode=DMA if available. Current= Not Applicable.
Second IDE channel =
Device 0/ Transfer mode=Dma if avail. BUT! Current Transfer Mode= PIO Mode.
Device1/Transfer=Dma if avail. Current=Ultra DMA Mode 3.
So, is my problem in the second IDE channel PIO mode or the Not applicable mode in my primary IDE channel?? please help.
