[FC4] CD / DVD RW issues

[M. Lewis]

I have a Sony DRU-530A that is giving me some issues.

Today I was going to to burn a CD and kept getting errors that there was 
no media in the drive. I switched several different CD's all giving the 
same results.

I tried playing an audio CD, no luck. It appears that it isn't even 
reading rhe CD.

I've burned CD's and played audio CD's in the machine before. So I would 
assume that one of the updates 'might' have caused some issues. Perhaps 
not though.

When starting K3B, it seems to be looking for CD devices for a rather 
long time.

In /var/log/messages I have lots of entries as follows:

00 00 "

There are no errors when booting the machine up.

The symlinks look ok:

[cajun at moe ~]$ ll /dev/dvd /dev/cdrom
lrwxrwxrwx  1 root root 3 Aug 25 16:33 /dev/cdrom -> hdc
lrwxrwxrwx  1 root root 3 Aug 25 16:33 /dev/dvd -> hdc


The strangest thing of all is I can put in a video DVD and it will play 
perfectly. No issues at all.

Anyone have any ideas on what might be the issue?

Thanks,
Mike
