 If it's an ATAPI cdrom, you might try hdparm -w /dev/cdrom.  N.B.:
 the -w option to hdparm is considered DANGEROUS.  If you have your
 CD-ROM driver compiled as a module, you could always rmmod/insmod
 again.

Thanks for the info.  I tried hdparm -w, which logged logged that it 
reset the device, but that didn't make any difference.  I then tried 
another CD-RW and that worked, so maybe I just have a CD-RW that has 
gone bad.

No disk / Wrong disk message when burning CD-RW

2007-11-17 Thread Larry Cook
I've got a FC3 system where burning to CD-RW works fine until the system 
has been up for a long time, at which point it gives the No disk / 
Wrong disk message.  I googled and found this:

---
Doing some Googling, for the No disk / Wrong disk message, I noticed
one person who said their drive burns just fine, unless the machine's
been on for a while.  Then it complains.  If they reboot, it becomes
happy again.  (I didn't notice if they mentioned what particular brand
of drive it was.)
---

which sounds exactly like my problem, but I did not find anything else 
helpful.

Has anyone seen or heard of this problem?

Is it likely to be a s/w or h/w problem?

Is there a way I can reset the device driver or the device itself w/o 
rebooting the system?

Thanks,
Larry

Yes. :)

If it's an ATAPI cdrom, you might try hdparm -w /dev/cdrom.  N.B.:
the -w option to hdparm is considered DANGEROUS.  If you have your
CD-ROM driver compiled as a module, you could always rmmod/insmod
again.

You might also want to look into any power management that might be
enabled for the drive... prehaps you're trying to burn a disk while
it's asleep. :)

Beyond that, it's hard to say w/o knowing what kernel/wodim version
and model drive you are using.
