Or does it let you browse RAW data? If the CD is all data (i.e. just one track): dd if=/dev/cdrom of=cd.iso bs=2048 If the CD is multiple tracks: for i in `/compat/linux/usr/bin/seq 1 100`; do dd if=/dev/acd0t$i of=track$i.cdr bs=2352; done Please see http://www.freebsd.org/doc/handbook/creating-cds.html, section 12.5.5. > Does it sound like not having put "fixate" on the end has made this CD > never again readable?

String together as many as you want, and just understand that it'll decrease the amount of data you can store on the drive. # Adam - -- Adam Weinberger adam@vectors.cx adamw@FreeBSD.ORG -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (FreeBSD) iD8DBQE91/fSo8KM2ULHQ/0RAiFQAKCRJZnSbyCJwgREkhzhTQQkspNvMwCdEmXd feG93l4sjR3Gee8XJm9faPU= =pWs0 -----END PGP SIGNATURE----- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
