K3B is a Linux CD/DVD burning application. I was recently using it to burn a DVD ISO image onto a DVD+RW disk, when I came across this error:
/dev/hdd: unable to proceed with recording: unable to unmount
Fatal error at startup: Device or resource busy
Unable to eject media.
This error hadn’t occurred the first time I burnt the blank disk (K3B automatically formatted it for me). But this time it turns out that because the disk actually has some content, the DVD drive has been automatically mounted by the OS – and this is now causing problems for K3B. Presumably it can’t issue the umount command when I run it because its not running as root.
To resolve this issue, as root, umount the volume:
umount /dev/hdd
Now try burning the disk again, and it should proceed.
Notes:
K3B can be installed on Fedora Linux using:
yum install k3b
Details:
Fedora Core 5 (2.6.16-1.2111_FC5), K3B 0.12.15 (Using KDE 3.5.2-0.2.fc5 Red Hat)

Thanks man! you solved my problem, only thing I have to figure now is how to automate this for every recording session
Oh I have to look at the k3b debug error code to take into account that in my case, the unmounting drive was hda, not hdd. The error said that it was unable to unmount hda because root is the only one allowed to execute unmount.
I was playing with umount last week, maybe I changed something, maybe in the permissions group? I’ll check this…
Thanks!!!
