I just tried to burn a CD for the first time in a long time
on a machine. The burncd(8) command worked fine on this machine
in FreeBSD 5.x (or was it 4.x?), but now in 6.2, I get,
# burncd -f /dev/acd0 -s 32 data hw.iso fixate
burncd: ioctl(CDIOCSTART): Input/output error
Looking at the dmesg(1) from the last boot,
# fgrep cd0 /var/run/dmesg.boot
acd0: CDROM <CRD-8400B/1.06> at ata1-master UDMA33
Makes me think the system is not recognizing the device as CDRW,
only CDROM. I get this from atacontrol(8),
# atacontrol info ata1
Master: acd0 <CRD-8400B/1.06> ATA/ATAPI revision 0
Slave: no device present
# atacontrol cap acd0
