burncd error

[Joe Talbott <josepht@xxxxxxxxxx>]

I get the following error when I try to burn a CD with burncd:

next writeable LBA 0
writing from file /home/josepht/tar-files/Minix-IDE-3.1.2a.iso size

only wrote -1 of 32768 bytes err=30

I believe this is EROFS.  Here's the relevant dmesg lines:

atapci0: <Intel ICH7M SATA controller> port

I also see these lines in dmesg:

Here's my uname output:

DragonFly hostname 1.9.0-DEVELOPMENT DragonFly

root@hostname:/home/obj/usr/src/sys/NEPTUNE  i386

Note: I'm still not running a NATA kernel.  I seem to remember reading
somewhere that CD-ROM drives on SATA controllers were not supported so
this may be what I'm running into.

Thanks,
Joe
