burncd: ioctl(CDRIOCFLUSH): Input/output error

[Richard Mahoney]

Readers,

I am having trouble burning CD-R's with the following:

[rbm49 at mahoney] ~ $ uname -a FreeBSD mahoney.remote.comnet.co.nz
4.9-STABLE FreeBSD 4.9-STABLE #0: Wed Oct 29 23:33:11 NZDT 2003
root at mahoney.remote.comnet.co.nz:/usr/home/obj/usr/src/sys/GENERIC
i386

mahoney# atacontrol list
ATA channel 0:
    Master:  ad0 <Maxtor 6E030L0/NAR61590> ATA/ATAPI rev 7
    Slave:       no device present
ATA channel 1:
    Master: acd0 <CRW1232/1.20> ATA/ATAPI rev 0
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    Slave:  afd0 <IOMEGA ZIP 250 ATAPI Floppy/51.G> ATA/ATAPI rev 0

[rbm49 at mahoney] ~ $ dmesg -a | less
[snip]
acd0: CD-RW <CRW1232> at ata1-master WDMA2

Typical messages follow this pattern:

[rbm49 at mahoney] ~ $ /usr/home/rbm49/bin/backup-scan

burncd: ioctl(CDRIOCFLUSH): Input/output error

The script I am using is:

[rbm49 at mahoney] ~ $ cat bin/backup-scan 
#!/bin/sh
#
# /usr/home/rbm49/bin/backup-scan
#
/usr/local/bin/mkisofs -U -R \
         -o /usr/home/share/temp/rbm49/scan.iso /usr/home/scan && \
/usr/sbin/burncd -s max -f /dev/acd0c data /usr/home/share/temp/rbm49/scan.iso fixate && \
rm -f /usr/home/share/temp/rbm49/scan.iso && exit 0
exit 2


Do any readers have any idea what the issue may be. This problem has
been occuring on and off for a while but appears to be becoming worse.


Best regards,

 Richard MAHONEY
