CD burning problem

[Jim Dishaw (dishawjp)]

To all those who were following this thread, I finally solved the issue.  For a quick recap, after upgrading 
from FC2 to FC3, I was no longer able to burn CD's.  I 
could not run cdrecord from the command line without 
getting the following error:
[code]
cdrecord: No write mode specified.
cdrecord: Asuming -tao mode.
cdrecord: Future versions of cdrecord may have different drive dependent defaults.
cdrecord: Continuing in 5 seconds...

We investigated my /etc/fstab. hal issues, cdrecord.conf, 
/proc/ide, and several other issues, but were unable to 
resolve the problem.

I found this thread:
http://www.linuxfactors.com/forum/showthread.php?s=4451c48f076d5e36eb8f70e78e4b8728&p=126126#post126126
and one other similar one and found that my problem was 
caused by changes made to cdrecord in FC3 which broke 
compatibility with my MSI CD RW drive.  This burner had 
worked just fine with RH8, RH9, FC1 and FC2.  As a matter 
of fact, since my computer is a dual boot FC2/FC3 box,
I could boot to FC2 and burn, but not burn in FC3.  So it 
wasn't a "bad" hardware issue.

I replaced my MSI CD RW with a new Memorex 52x32x52x unit 
and it burns like a champ.  From Nautilus, with k3b and 
from the command line with cdrecord.

Thanks to all who worked with me and offered suggestions 
and advice in fixing this.  I just wanted to post this here 
in case someone else is searching these archives with a 
similar problem or has been following this thread.

Thanks again,

Jim Dishaw
