cd burner: how to prevent buffer under run or any other probs

[shaggy2dope]

i have a sony CD-R 6x and a 36x atapi cd rom i have been wasting alot of cds to errors like buffer under run and some other errors mainly buffer under run i want to copy music musics cds running 98 350 mhz

[AuraEdge]

Try running it at 2x
I have a Sony 2x/8x and if i dont touch the comp while burning, i NEVER get an underun
I also have the CD-r on its own IDE cable (and normal CD rom and HDD on the other)

here are some links to help you out

I would suggest that you learn what you are doing with cdrw's and then go to cdr its much cheaper than making coasters

good luck

thanks i cant run my cd-r on its own cable because i also have a zip drive so all my slots are full i set my cd rom to a slave is that the problem?

Set writer to master.
Be sure you don't have anti-Virus running.

Hit Ctrl-Alt-Delete and close all the programs except explorer. Then do your burning. I have my CD-Rom on the Secondary Master and the Burner on the Secondary Slave. I also know that the Burner doesn't like DMA enabled. So i can't enable the DMA on my CD-Rom either when it comes to burning.

Hope this helps.

how do i disable the DMA?

thanks jim i disabled DMA on my cd rom do i disable it on my burner too?

Something else you need to pay special attention to is the speed at which your 36x ATAPI CDROM is capable of performing digital audio extraction.

For instance, my 40x Plextor CDROM is only capable of digital audio extraction at 12x!

If you try to burn at a speed that is faster than the digital audio extraction rate of your 36x drive, then you will continue to get buffer under-runs, regardless of the tweaking you do.

Get a SCSI drive. I've had all kinds of problems with the IDE ones with SCSI drives I haven't burnt a coaster yet.

the error ratio goes down considerably when you burn above 2x, thats why you have the option to burn at any speed. At 2x, i have yet to burn a coaster, and i have burned around 40 music cds and a few dozen data cds.

A buffer underrun error means that, for some reason, the flow of data from hard disk to CD recorder was interrupted long enough for the CD recorder's buffer to be emptied, and writing was halted.
If you have more than 16 MB of RAM, change the hard drive's Typical Role to Network Server. This gives the HDD a higer priority than other devices, and should allow a clean fast transfer of data to the burner's buffer, reducing the underrun chance of error


Copying audio digitally from a CD requires a CD-ROM drive or CD recorder which supports digital audio extraction (DAE). All CD recorders can perform DAE. Many CD-ROM drives do not support DAE at all; others do it, but not very well. Few (if any) high speed CD-ROM drives can extract audio successfully at or even near their top-rated data speed.
Unsuccessful audio extraction is easy to detect; it sounds bad (clicks, pops, or hissing within the track). The most common reason is that DAE is being performed at too high a speed for your source CD-ROM or CD recorder to maintain proper synchronization of the audio data it is passing to the hard disk or CD recorder. Audio samples are skipped or repeated, causing errors which sound to the human ear like clicks, pops, or hiss.

The solution is to slow down DAE. However, with some drives, getting a clean audio extraction requires reading at very slow speeds. Sometimes the drive will go back and re-read the same audio samples over again to make sure that everything is in the right place. At times, the read will be so slow that it is impossible to copy directly from your source audio CD to the CD recorder, because the read speed is slower than the recorder's write speed. In this case, you will have to copy the audio tracks to hard disk and then record them back to CD.

*conclusion*
If copying to the HDD first, keep the burner and source HDD on a seperate channel, and have a system that supports Dual FIFO!

Since you seem to be doing a lotta CD-to-CD copying, I'd suggest your HDD and CDROM as Master and Slave respectively on IDE 1 and CD Writer and Zip as Master and Slave on IDE 2. This way, HDD and CD copying would be better.
