Oh yes it will, AFAIK. But the CDRW needs to be formatted for packet
writing first....
To Shawover and above this answer and others you've received, my
advice is that you do *not* do this.
CDRWs are less reliable than CDRs, and packet writing is less reliable than
normal CD-writing. Saving a few cents on your backups, but ending up with
less reliability makes no sense.
