I dunno about all this other stuff, but to me, *THIS* looks like you don't
have the IDE-SCSI module installed.

The IDE-SCSI module "fools" the OS into believing your IDE CDRW device is
"really" a SCSI device.

Without that, cdrecord can't work, since it works through the SCSI interface.

Under RedHat, you would find/download/install the ide-scsi software, and
then do "insmod ide-scsi"

You might also need to make some devices /dev/pg0 etc -- It's all in an
FAQ somewheres for cdrecord.

I gather from my minimal experience with FreeBSD that you'd be doing
something more like pkgload (?) but the principle remains the same:  You
need a module to "fool" the OS into believing your CD/DVD burner is SCSI
when it's not, or cdrecord simply won't talk to it.

> cd0: <TOSHIBA DVD-ROM SD-R6112 1031> Removable CD-ROM SCSI-0 device

This, however, indicates that it *IS* a SCSI device...

And its number is "0"

In which case, I would start with:

cdrecord dev=0,0,0 -data whatever.iso

> <TOSHIBA DVD-ROM SD-R6112 1031>	at scbus1 target 0 lun 0 (pass0, cd0)


Also try:

cdrecord dev=1,0,0 -data whatever.iso

as it seems to be on bus 1.

Do all of this as 'root'  If you can get it to work as root, then evaluate
how badly you need it to work for other users, and what "holes" you open
up to do so.

Like Music?
