Image burning on multiple optical drives

If anybody knows how to solve this, please let me know right away, i dont want to go out and have to do the "last resort" option! :(:(

I just bought a sony dru 710A dual layer drive. I have that and a nec dvd+rw drive on the same cable. the sony is set to master, and the nec is set to slave. Before i bought the DRU, my NEC write speeds for burning images was going at 4x i believe, wrote my images pretty quick (3-4 gig size images). Now after i had installed above setup, i noticed that the nec was now burning at 1.3x and lower, but not over 1.3x, although i had said for it to burn at max (4x), or even just 2x. Didnt matter which one i chose, it always burned at max of 1.3x. This took forever burning the images of 3 and 4 gigs. I do this alot because i distrubute discs for people via dvd, and the demand is high and i need a faster speed. These dvd's are TDK dvd+r's. How come the write speed has cut down to below 2x?? I have heard that maybe its because its set to slave, and data goes through master on the ribbon cable, to slave, slowing down transfer speeds, but isnt that when both drives are being used? please help :(
 
have you tried to change them around so setting the NEC on the main ide channel and sony on the second!
 
IDE can only access one drive at a time, so it's highly likely that having IDE drives on one channel is forcing the data to switch between each.

The other thing you could check is make sure that DMA is enabled on these IDE channels.
 
yeah sniper, that is something i should of tried already, but i just wanted to see if there is something that isnt enabled or w/e. i am going to try out big's suggestion first....which brings me this Q, how do i check to see if both channels are using DMA? i have xp pro

thx
 
i jumped the NEC to master, and the Sony to slave, and not :cool: to my surprise, it worked. i was right after all, with the sharing of bandwidth, or should i say redirected bandwidth. Glad its working agian, let the dvd ripping begin! :D At 3x the speed!! thx for your help guys :good:
 
To check for DMA under XP, go into device manager, and expand IDE ATA/ATAPI controllers. Double click on the Primary and/or Secondary IDE channel that the burners are on. Both Device 0 and Device 1 should be set to DMA if available. If not change it. If you can't you may need to install your chipset drivers, but the Standard IDE driver in Windows should allow you to use it just fine. You may have to reboot after changing these settings.
