Help with Multiple Burning Simutaneously

[calman]

I have been trying to use two burners at the same time with virtural drives as the sources. Using Alcohol 120% program as this the one I have to use for the type of file format I'm burning.

I start burning with the first burner then after is underway I load the second Alcohol program and start burning the second disk. Now I have successfully done this once. But must have been just luck as I have had no success again. The problem is the physical buffer memory on the second drives detoriates to a level not sufficent to continue burning and I end up with a coaster. Now my system is a Amd 1800, 512 megs DDR., 80 gig hd. Both burners on the secondary and the hd on the primary. Is there a special set up required to do multiple burning at the same time?
Thanks in advance for any advise.

if both burners are on the same channel, they are splitting time on the line. there is nothing you can do about that. this is the same problem when trying to do on the fly copies. you are also putting a double strain on the hdd if you are accessing it simultaneously. why do you need to multiple burns at the same time anyway?

I have quite a few disk to write and being I have to write them at the 4x speed, it takes quite a while to burn approx. 600 megs per
disk because they are audio cds and because they have graphics involved with the wave files, that is the speed I have to write at . Now being that Alcohol has the multi program open option, they developed into their program, and I have two burners. Why not? Save some time. Yes it does put double duty on the hd, but at only 4x this is approx. 1200 kilo bites per sec. I thought it wasn't that much of a reading stress. As the programs indicates that it is a memory buffer problem, I thought there might be a setting in windows or a hardware or extra program that is required to achieve what I am trying to do without damaging my
system in anyway.

Why not upgrade to two new high speed burners and drop the 4X speeds!

My 48X Plextor has an 8Mbit buffer (I think) and it would be perfect for multiple copies with a second burner.

you could try getting an additional pci ata controller and see if that works. have each drive on its own channel. you are still putting a strain on the pci bus, though.

I just bought my Plexter 52 speed and it only has 2 meg Buffer and my TDK 40/48 has a 4 meg buffer, the latest Plexter I believe only have a 2 meg Buffer. I have to record at 4x, its the only way I can achieve quality results with the type of files I am recording.

I am going to put the Plexter on the secondary by itself, because of the 2 meg buffer and the TDK on the primary as slave with the hard drive, being it has 4 meg buffer. This would be passing the
data to each cdrw on different channels. The max. physical memory buffer Alcohol will use is 128 megs. and it seems to want it all, and leaves little to the second Alcohol to operate with. Maybe I'm being lead down dead end road with Alcohol having a box to check off or on if you want to use multiple programs.

With the new cdrw these days I haven't made a coaster since I
don't know when. But when I started trying this I have come to know how it felt. LOL Its a good thing disks are cheaper these days, it gives more room for trying. :)
