A not-so-known thing about FreeBSD:
I wanted to duplicate a disk, but couldn't for the life of me get it to work - how the H#&& do I get the SCSI-emulator to work, grrrr!!
Then I found burncd, worked right off the IDE, just like I would have done it.
".. just like I would have ... hmm, lets try .."

# cat /dev/acd0 >file.iso

YES! That is the way to duplicate a disk under FreeBSD:

You cat the CD and pipe it to the CD-R!

I became a _dedicated_ BSD fan after that :-)
