Re: Problems burning CD-R's with Plextor PX-708A and cdrecord

2004-01-27 Thread jeff beck
Thanks for the suggestions regarding DMA, its just odd
that my 8X Sony CD-R CRX140E in the same box works
fine at 8X but the brand new 40X Plextor only works at
4X unless I turn on burn-free.  Burning data underruns
as well.

I am not running out of CPU to feed the burner ... the
box is very nearly idle when burning either with the
Sony or the Plextor.  With the Sony I never have a
problem using my mail program, browsing the web, etc.
while burning.

My question, then, is what does Joerg Schilling means
when he says, CDs with Burnfree are of worse
quality. in the following post:
http://lists.debian.org/cdwrite/2003/cdwrite-200311/msg00127.html

With data, I'm not sure how much I care, but I am
quite concerned about audio quality - will enabling
burnfree cause audio quality to suffer?

Thanks for any help you can offer,

 I have tried using the cdrecord that comes with my
 redhat9, current binaries, or, as you see now, the
 latest alpha.  I upgraded my firmware to 1.04.

 My burner is primary-slave, the wav files are on
 secondary-master.  I have DMA enabled everywhere.
 Changing the speed and turning off pad or dao seem to
 make no difference.  As I mentioned, burnfree works
 great.

If you're burning audio CD's on Linux 2.4, be aware that DMA is only 
supported for a block sizes that are multiples of 512 there, while 
burning audio uses larger blocks (2352 bytes?).

How does burning data discs go? If that works fine, then this is 
probably the problem.

write error - loss of streaming definitely is a buffer underrun 
though, which matches the fact that enabling burnfree fixes the 
problem.

# cdrecord dev=0,0,0 -v -pad -dao -speed=16 -eject

I have several thoughts, although none quaifies as an explanation. If 
you are using any kernel but a 2.6.x AFAIK the audio mode doesn't use 
DMA. You may also need the latest 2.01a25 cdrtools for that, but you are 
using that version, hopefully built with patching to actually find and 
use the kernel include files for the running kernel.

If you have a 2.6 kernel, you can see if DMA is working by starting an 
audio burn and using vmstat 1 to watch the system time. If it uses 
only a few percent DMA is working.

If it is NOT using DMA you may simply be running out ofCPU to feed the 
burner. You can certainly try increasing the size of the fifo buffer, 
assuming you have a typical RAM size, maybe fs=20m or so. This gives 
you a little hedge against problems, although the issue is not a failure 
to keep the fifo full. You could also try without -dao, that may slow 
the burn but result in success. I haven't looked into why that's so, but 
on a system *with* DMA working, I found that with DAO the burn time for 
my test data was 146 sec, and without was 210 sec, burning two examples 
of each.

You could always use a lower speed, of course, I had to do that on one 
of my systems with a similar problem. Hope this helps.

Only halfway correct as most of your replies in the past :-(

The fact that the interfaces used for generic SCSI to ATAPI drives
don't use DMA if the transfer size is not a multipe of 512 is known 
for a long time. Unfortunately, the important Linux kernel poeple 
are not really interested to fix this bug - they even admid that
they don't own a CD/DVD writer and don't plan to buy one :-(

Last year, I did again send oud a bug report..

... the result was _not_ to fix the known bugs but to first introduce
a new unneeded new interface that in the first attempt did have the same
DMA bug! Later, they did fix the DMA bug only in the unneeded new interface.

Call it how you like, my impression is that this is pure evilness.

As the fact of not having DMA for audio transfers is bug, the fact that
it is possible to have DMA with an unneeded interface on Linux-2.6 is not
a feature but just an incomplete fix for a bug.

Problems burning CD-R's with Plextor PX-708A and cdrecord
