Well, the idea is that you get one device pr CD track, that way you can do what you want with them, ie to rip audio track 4 you do: dd if=/dev/acdNt4 of=track4.raw bs=2352 To mount data track5 with an ISO filesys: mount -t cd9660 /dev/acdNt5 /cdrom If you want to collect all audio tracks together you would just use the normal /dev/acd0c device, read the TOC of the CD so you know where they are, set the right blocksize, and there you go (that works now BTW). -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
