2 52x cdrw, getting no where close to maxium burn speed!!???

Okay, i just bought 2 brand new cdrw and installed them...and when I burn i am getting ONLY like 5x average, and I have dma checked. i have a 2 gig system, etc... my hard drive is rather old, 7-8 years old, so it's probably slower than the cdrws???

my hard is drive is primary master, and my sony 52x32x52 is secondary master, with my norcent 52x32x52 (really a liteon) is secondary slave...

is this the ideal setup??? strangely when do "disc copy" from cdrw to cdrw, if i use sony as destination drive, and norcent as source, I do get an increase of speed, but it's still only 20x at best, and if i do it vice versa, then 5-8x average..

I never thought it would be this complicated buying two high speed drives..

help!!!

Well, how fast is your hdd? I doubt it really has "that" much to do with it, what about the cd media? Is it labled 52x? Also, have you thought that doing copy to copy from 2 different drives will slow it down? For instance, one has to read and one has to write, and they only way that will work very well is to have a big load of ram and a big PSU to power it all.

mainly it is because the same bus is doing double the amount of work
reading and burning at the same time

i would put the read drive as primary slave
and burner as secondary master

give that a try

ah the great cd rom speed myth

the 52x is refferring to cdrom read speed not cdrw write speed

and the myth is that there 1 realy speed more or less for reading 50x and 20x doesnt make much difference

ur write speed should be higher than 5x but not much higher my dvd writer only gets 2.4x

umm.. tard? his write and read are both 52x lol..

cd rom speed myth!!!!

well, the myth to which prom speaks goes more like this, cd's themselves aren't really meant to be spun at more than 48x, so many drives are capable of the higher speed burning themselves, but won't spin the drive that fast b/c it can shatter a cd (i've seen someone disable the limiter and the cd shatter in the tray). As far as getting 5x speeds, most of the above, regardless of how you have your drives arranged, should be causing that. I don't have an answer for you, but the power supply explanation seems most plausible, though i wouldn't think that'd be the problem.

are you reading with one drive and burning with the other at the same time? i find that if a have CD's that burn at 52x and i make and LCD image on my hardrive - itll do a CD in about oh... 1m:12s - and thats on a relatively old computer.

of course it could be your CPU. cuz b4 i upgraded mine - anything above 4x would buffer underrun.

yea but 48x doesn't - 5x..
