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

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 it working...

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.  I gives the above
errors for cdrw discs.

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