Acer CDRW [ burncd: ioctl(CDRIOCBLANK): Device busy ]

[Matt Gostick]

I'm having a bad month.  My harddrive died and I lost ALOT of data that is gonna take time to get back, I didn't have a good backup policy.  I now have installed a cd-rewriter into my box, and plan to burn a cd once a week or so.  My problem is that I can't seem to get is working...  even though I've the same drive working on another FreeBSD box.

FreeBSD nowhere.nowhere.com 5.1-RELEASE FreeBSD 5.1-RELEASE #0: Thu Nov 27 23:17:53 EST 2003     root at nowhere.nowhere.com:/usr/src/sys/i386/compile/NOWHERE  i386

gaspra# burncd -f /dev/acd0c blank
burncd: ioctl(CDRIOCBLANK): Device busy

gaspra# /usr/sbin/burncd -f /dev/acd0 data /backup.iso fixate
burncd: ioctl(CDIOCSTART): Input/output error

When I burn with a normal cdr disc, it works fine.

What does this mean?  How do I fix it?  A search on google and the mail list doesn't exactly report a slew or questions or answers.

Thanks,
Matt.
