Something very odd is happening with these disks.  I get errors, as I

that it doesn't exist.

I just talked about this very subject on the fedora beta list.  It seems
if I burn a new cd-rw disk, it seems to work fine.  But if I try to
reburn it, it wouldn't do it.  I think someone mentioned that they
unmounted it and it still had problems.


I'm fairly sure that I've tracked it down, Mike.

Someone told me off-list to try to burn a short iso using cdrecord in a terminal. The command I used was

cdrecord dev=/dev/hdd -vvvvvvvv -blank=disc /home/anne/test.iso

and it failed. I googled on 'faio_wait_on_buffer for writer timed out' and found that others were complaining of the same problem. Then someone reported that if you split the command into two, it works perfectly, so I did

cdrecord -vv dev=/dev/hdd blank=all
cdrecord -vv dev=/dev/hdd /home/anne/test.iso

and it wrote perfectly - this to a disk that k3b had been totally unable to deal with.

It looks as though there is actually a bug in cdrecord, which is causing k3b to fail.

Nice catch!

Which versions of cdrecord and k3b are you using?

Thanks,

John
