Hi Sue, For jargon-busting purposes, I've found the CD-R FAQ at http://www.cdrfaq.org/ to be most useful... lots of information you'll never need, but probably everything you do need to know is there. > Here's where I'm at so far. > > FreeBSD set.welearn.com.au 4.4-RELEASE FreeBSD 4.4-RELEASE #1: Wed Dec 26 09:32:11 EST 2001 root@set.welearn.com.au:/local/src/sys/compile/SET i386 > acd0: CD-RW <SAMSUNG CD-R/RW DRIVE SW-224B> at ata1-master using PIO4 > acd1: CDROM <ATAPI CDROM> at ata1-slave using PIO4 > lrwxr-xr-x 1 root wheel 5 Jan 20 01:57 cdrom -> acd1c > lrwxr-xr-x 1 root wheel 5 Jan 20 01:57 cdwriter -> acd0c > > I've read the burncd man page, then found Dan O'Connor's tutorial > at http://www.mostgraveconcern.com/freebsd/ and from that made > some sense of what the man pages tried to tell me.

So far I see that you can make an image of a data (or > audio??) CD with a command like > dd if=/dev/cdrom of=filename.iso bs=2048 > but I don't know whether I can just change it to of=/dev/cdwriter > to do the whole job in one action, or use a pipe to a burncd command, > or does it only work via an ISO image on the hard disk? I think you'd need to pipe that through burncd -- the drive will need to be told to do things like turn on the write laser, finalise the CD, etc., which are not part of the ISO file. Also, you're quite likely to have problems with a CD-to-CD copy when both drives are on the same IDE bus, as yours seem to be. IDE devices often aren't too good at sharing the bus, so there's a good chance of buffer underruns. Unless you can move one of those drives onto a different IDE chain, I'd stick to copying onto the hard disk first.
