Hello everybody,
Sorry about all the confusion the past few days -
but
I really suspect things are terrible wrong when I
burn
CDs: both data CDs and debian installation cds
seem to
be malfunctioning !!
I should have tested data CDs more before - but
today
I found those can't be mounted - just like the
debian
installation cds which can't be read completely
I using this shell script to burn:
#!/bin/sh
mkisofs -r -o cd_image "$1/"
cdrecord -v speed=24 blank=all dev=0,1,0 -data
cd_image
cdrecord -v -eject speed=24 dev=0,1,0 cd_image
I'd try only the one invocation of cdrecord. Delete
the line with
blank=all in it. Iff you are using CD-RWs do the
blanking as a
separate, preceding step, by hand.
As I didn't know exactly how to do blanking by hand, I
tried xcdroast - however, that program uses cdrecord
too so it doesn't solve anything - what's the program
to use for blanking ?
When copying the contents off the cd, I get the
following error output:
hdc: cdrom_decode_status: status=0x51 { DriveReady
SeekCompleteError }
hdc: cdrom_decode_status: error=0x30
during the hole damn cd writing process, not a
single
other (custom) proces was running; One thing which
feels wrong is, at first the fifo was 100% or 98%
-
but after some time it rapidly dropped to very low
values ( < 10% ) - however, I don't know wether
this
has something to do with the incorrect burning
I should say it probably does. I don't think
"burnproof" drives are
guaranteed 100% "burnproof" under all conditions.
What is the minimum fifo fill reported by cdrecord
when it finishes?
I'm not sure, but I think it was extremely low (only a
few %)
What sort of HD/MB/CPU have you got?
Sorry I don't know the exact numbers - my dad has the
info *somewhere* here but I can't find it;
Try setting speed=2 or something similarly slow and
see if your fifo
fill levels improve. Use the -dummy option to
experiment without
wasting CD-Rs.
I tried the following commend:
cdrecord -v -eject -dummy -force speed=2 dev=0,1,0
cd_image
The speed seemed to be 98%/100% the hole time - and
the minimum fifo fill was 81% - do you think this is a
reasonable number (say, enough to assume this will
work correctly) or should I try speed=1 ?
I was using the high value of speed=24 because that's
what the cd writer reports (48x24x48) - well any way
that's too much I see now.
