I am having trouble burning an iso image to a CD-R using FreeBSD 4.10. I have tried using
burncd , cdrecord, and growifofs, all appear to have basically the same problem (see details below)
"Operation not permitted". The only thing bugs me is dmesg reports my drive as a DVD-R.
I am not sure if this is the problem or how to addressing correcting it if it is. Note: the BIOS
report the drive to be TOSHIBA DVD-ROM SD-R6112 1031.

Can anyone give me some direction as to what I should try next, or better, I can the burner working?


FYI: I read the CD-Writing Howto and several other articles and followed
the instructions therein to the best of my ability (you be the judge). This

- logging in as root;
- adding "device atapicam" to the kernel configuration and rebuilding the kernel;
- creating /etc/devfs.conf as follows:

link    acd0    cdrom
link    acd0    dvd
perm    acd0    0660
perm    cd0     0660
perm    pass0   0660
perm    pass1   0660
perm    pass2   0660
perm    pass3   0660
perm    xpt0    0666

- installing cdrecord, dvd+rw-tools
- ensure that the drive can read CD's and DVDs - running ./MAKEDEV pass10 in the /dev directory

also added these


to /boot/loader.conf

mount -t cd9660 /dev/cd0 /cdrom         # works fine CD's and DVD's

Here's some things I tried:

burncd -f /dev/acd0c -s 12 data 5.2.1-RELEASE-i386-disc1.iso fixate
burncd: open(/dev/acd0c): Operation not permitted

cdrecord -scanbus
Cdrecord 2.00.3 (I386 .....
