so i need a NEW hard drive?

Could be.
I'm not totally sure, but you say your harddrive bursts at 10.5MB/s

To write at 52x, you need a sustained speed of 7.8MB/s for the outer most rim, but your harddrive cant even maintain that, so its probably not writing at its full capable speed til somewere near the middle or the end of the burn.

A 52x burner should take around 3 minutes to burn, but don't get a harddrive just to save 8 minutes off a burn. If you need more GB anyways, then get a new harddrive.

Before you get that new HDD, I'd make sure that that you have the latest drivers for your motherboards chipset, whatever it may be, and after that, that you have DMA enabled on both the HDD and the CD-RW (in the BIOS and in Windows) - The speeds are slow enough that DMA may not be enabled, which limits speeds to 16.6MB/s in the fastest PIO mode.

BTW, I think sync data transfer and disconnect are SCSI device related items, so they ld be left at default if the devices are not SCSI. Probably wont do anything if you change them anyways.

Right, your major bottleneck in CD writing is ALWAYS hard disk throughput.
And of course, the CDRW should never be on the same IDE cable as its data sources (the HDD most of the time).

maybe that's my problem, my hdd is not on DMA, I'll enable it and see what happens. Thankd, If any of you still have suggestion, kepp'em comin, !!!

Webmaster_Trent · May 23rd, 2003, 04:18 PM

omg,omg,omg,omg! I am sorry... But your suggestion worked. I enabled DMA on my HDD and now is at burst read speed of 26.1 and random access is about 1 ms better. Now to burn the CD, i'll brb..

Well i'm back and i have some bad news. It didn't work. For a AUDIO CD which was about half of the whole cd capacity it took 6:36!!! No like i have said before, i don't mind 3:00 minutes for a half of a cd and 6:00 for a whole cd, but 12 minutes for a whole and 6 minutes for a half!!! Any more suggestions anyone?( i plan to go get that IDE cable, just for the heck of it......hmmm?)

Since i turned DMA on(on my HDD), it seems to go a little faster, or maybe it's my imagination?

AuraEdge · May 23rd, 2003, 08:00 PM

Is the lite-on on DMA as well?

Also, like PeterM suggested, CD-RW should be on a different IDE cable as the source data (HDD in this case) whenever possible to get the fastest speeds.

I'm not entirely sure its the harddrive anymore, but I'm inclined to point a finger at the old super 7 chipset. Not sure what kind of throughput a super 7 can sustain, but the technology is pretty old. I don't think it'd be worth finding out what exactly is your bottleneck to save a few minutes off your burn, because itll cost more than its worth, and you might diagnose the wrong part and end up spending money on something that doesnt even solve your problem.

Why not set the burner to burn the CD's at 24X?

If the program finds the max speed of the CDR is 24, and you have it set to 52, it may just have a "fallback" of 8x.

Also, you might try a different burning program. I see you're already using nero, you might try a demo of another just to make sure.

All Super-7 chipsets had at least UDMA mode 2 support on IDE, the later ones even mode 4 (33 and 66 MB/s respectively). This is not going to hold you back; neither will the CPU since it practically isn't used while the drives are DMAing data back and forth from system RAM.

Can anyone tell me this: If my IDE cable is 9 years old now, could it be too old and i would get TOO slow of speeds??

I original had bought a ACER with a pentium, i think 66mhz, not sure though. IT cam with a 2x cd-rom. and everything ect. I upgraded my system in 1999 to a AMD K6-2(500mhz) and a super 7 socket, Gigabyte Ga-5aa . Now, i am not sure if the people who upgraded my computer upgraded the IDE cable. Just any idea, anyone think it could be slowing it down?

Ohh yes.... 9 years old!!!

you are probably using an IDE cable that only supports 66mhz...

you should at least have 100mhz or 133mhz IDE cable.

try changing the Cable.
