CD/DVD writer no longer works

[Paul Schmehl]

Sometime in the past (I don't know when) my CD/DVD write device stopped 
working.  I can no longer burn cds or even put known good cds in the drive 
and mount them.  I *used* to be able to burn cds fine using burncd.

root at utd59514# burncd -ef /dev/acd1 data 
/home/pauls/Downloads/FreeBSD/6.2-RELEASE-amd64-disc1.iso fixate
burncd: ioctl(CDRIOCWRITESPEED): Input/output error
root at utd59514# mount /dev/acd
acd0  acd1
root at utd59514# mount /dev/acd1 /mnt/cdrom/
mount: /dev/acd1: Input/output error

I'm wondering where to go to troubleshoot this problem.

I'm loading atapicam.

I can see the device using atacontrol.
root at utd59514# atacontrol info ata0
Master: acd0 <HL-DT-STDVD-ROM GDR8163B/0D20> ATA/ATAPI revision 6
Slave:  acd1 <TSSTcorpCD-RW TS-H292B/DE03> ATA/ATAPI revision 5

I can tell what mode the device is in.
root at utd59514# atacontrol mode acd1
current mode = UDMA33

The channel reinits without errors.
root at utd59514# atacontrol reinit ata0
Master: acd0 <HL-DT-STDVD-ROM GDR8163B/0D20> ATA/ATAPI revision 6
Slave:  acd1 <TSSTcorpCD-RW TS-H292B/DE03> ATA/ATAPI revision 5

Camcontrol sees the device fine as well.
root at utd59514# camcontrol devlist
<Maxtor 3200 0344>                 at scbus0 target 0 lun 0 (da0,pass0)

<TSSTcorp CD-RW   TS-H292B DE03>   at scbus1 target 1 lun 0 (cd1,pass2)

Yet cdrecord also fails.

/home/pauls/Downloads/FreeBSD/6.2-RELEASE-amd64-disc1.iso

I just upgraded from FreeBSD 6.0 RELEASE to 6.2 RELEASE hoping that might 
solve the problem.  (I cvsupped the sources and ran make 
buildworld/buildkernel, etc.)

Do I have a hardware failure?  Or is something else wrong?
