Guys, this has been in my head for a long time.

Even though my CDROM is a 52X one (max 7800bytes/sec), why is it at about 2500bytes/sec all the time. It surely can't be something wrong with the CDROM, can it? Is Windows making him slow. All the CDROMs I've seen ork at that speed. Then what is the purpose of buying CDROMs with higher read speed? :(

If there's any program that can make CDROMs read CDs faster, then let me know

Wich program need 7800bytes/sec ?

What cable type are you using?

And also, do you have DMA enabled? Enabling that allows direct transfer from memory to your writer without the CPU getting involved - it just might get things a bit quicker for you.

I was just about to ask this question in BetaONE :)

Can you please tell me as well, how to enable DMA in Windows XP?
The Nero Burning ROM's Nero Info Tool shows my CDRW is DMA Off....:o

I know how to make it enable in Windows 98. But that way is not possible in Windows XP....:(

Click on the transfer mode box to select between PIO mode and DMA mode. Choose DMA mode to enable DMA mode for your hard disks and CD-ROM. The Current Transfer Mode box indicates whether DMA mode has been enabled for your IDE devices or not!!!!

You are dA MaN !
Thanks heaps....:)

Thanks for all those trouble, print-screen, saving, and uploading the pics....:)
Gonna print this topic...yes to PDF :)

Nice job deadman :D

Thanks, Norm!

I appreciated too...:(

Still after enabling DMA, I couldn't get the optimum performance.
I could copy a 187MB folder on a CD to the hard disk at below read speeds

40X max - 61 seconds
52X max - 49 seconds
(My CDROM can read disks at both these maximum speeds, it's a Sony CDU5211)

So that means I only could achieve 3MB/sec and 3.8MB/sec instead of 6MB/sec and 7.8MB/sec.
If the CD was written in a slow speed, does this slow down the read speed of the CDROM? I
think this might be the case.

Hmmmm?????????????

I am pretty sure the written speed doesn't affect the reading speed. lol. This should be something else. Remember, we can't expect a 100% efficiency in any device in the present world.

What kind of cabling are you using? afaik the newer ata133 need to be installed only one way. Some people put them in backwards to be able to reach the cdrom at the top of the case. In other words, the longest part of the cable (between ide connectors) should start at the mb, then the hd then the cdrom. I did this once and the transfer speeds deteriorated.

Do 52x really do 52x? Atleast a year ago it wasnt common that cdroms really read as fast as they said.

Well when I bought my new 52x and plug it in it was going at 40x.

However I changed it back to 52x using some program. Dont remember what. Might be WinGuides Tweak Manager.

um oh yea winboost 2001 but not 52x

Adjust CD-ROM cache up to 48x speed/DVD-ROM speed up to 6x speed

Kinda old now but 48x is better than 40x
