cd burning problem

[Joris Huizer <jorishuizer@planet.nl>]

Hello,

Sorry for reposting -- I accidentilly removed the mails from 
debian-users without checking wether my question was answered (it 
doesn't show up in the debian logs though)

I tried kernel 2.6.8 and it worked fine -- but I got myself into a cd
burning problem.
The first time under kernel 2.6.8 , cdrecord did work, but because of
too much business in the computer (other programs running, and the fact
that cdrecord seems to try and get to the maximal speed, somehow) the
written file wasn't burned correctly;
After that problems started, it doesn't allow to burn, also not in (a
custom) 2.6.7 kernel;

`cdrecord -scanbus` replies,

cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open
SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'.

cdrecord: package and read /usr/share/doc/cdrecord/README.ATAPI.setup .

`cdrecord -scanbus`  used to report that the target is at ATAPI:1,0,0;
I usually use
  mkisofs -iso-level 1 -graft-points
"/jhbackup.bz2"=/tmp/jhuizer.tar.bz2|cdrecord dev=ATA:1,0,0 gracetime=2 -v -

which I have put in a shell script so I don't have to remember all those
flags ;)

I'll use kernel 2.6.7 for now as it used to burn without any problems;
can anybody tell me how to find out what is wrong (and how to fix it?)

Thanks for any help,

Joris
