How can I use dd to copy a CD? The command below does not
work - I presume I have failed to understand something. I have tried other
devices begining "acd".

What kind of data is on the CD? Whether or not you can/should use dd
depends on what you're trying to do and with what kind of CD. Make sure
you read chapter 12.5 of the FreeBSD handbook.

It is a data CD. "bs=2048" was what I needed. My thanks to all who made suggestions.
