Well, I'm sorry to say that it looks like I've found the answer to my own
question.  I found after this posting (by looking at dmesg) that I was
getting the following error.
	acd0: rezero failed

I did some searching and found several postings in -current that said my
drive, a MITSUMI CR-2600TE, does not support the REZERO command and is
therefore not going to work, at least with the acd driver I have running

Now my question is, and this is why I'm cc:ing this to -current is, has this
particular problem been addressed in the current release(s) of FreeBSD.  The
thread that addressed this particular issue (in -current) was about 5 months

Incase anyone was interested the URL to that thread is..

Thanks again, guess I'll be putting the burner back in the winblowz 98
machine unless someone can help me out with a fix.

Subject: unable to use cdrecord on an ATAPI CD-R under 2.2.8.

 I'm trying to use my ATAPI cd-r on my 2.2.8 box and am having no success at
I have the acd device in my kernel and it detects just fine upone startup.
And I can mount /dev/wcd0c just fine.

	acd0: drive speed 1377KB/sec, 2048KB cache
	acd0: supported read  types: CD-R, CD-RW, CD-DA
	acd0: supported write types: CD-R, test write
	acd0: Audio: play, 2 volume levels
	acd0: Mechanism: ejectable tray
	acd0: Medium: no/blank disc inside, unlocked

I have tried to use the cdrecord's -scanbus option to try and get starting
and what I get is the following...

	Cdrecord release 1.6.1 Copyright (C) 1995-1998 Jörg Schilling
	cdrecord: No such file or directory. Cannot open SCSI driver.

Ok, it uses /dev/scgx, so I did 'ln -s /dev/rcd0.ctl /dev/scgx' and I still
get the above error.

So NOW i'm trying to specify the device name on the command line, as it says
on the man page I can do.  'cdrecord -scanbus dev=/dev/rcd0.ctl:0,4,0'
	Cdrecord release 1.6.1 Copyright (C) 1995-1998 Jörg Schilling
	scsidev: '/dev/rcd0.ctl:0,4,0'
	devname: '/dev/rcd0.ctl'
	scsibus: 0 target: 4 lun: 0
	cdrecord: Device not configured. Cannot open SCSI driver.

If i try similar things such as /dev/rcd0a, /dev/rcd0c, I get the same above
I've tried MAKEDEV wcd0, acd0, rcd0.  With no luck.. MAKEDEV doesn't even
recognize acd0.  SO, I'm out of ideas, I know others out there are using
this thing because I see enough traffic on the mailing list.  But does
anyone out there know how to help me with this issue?
