I hate to sound like a broken record, but the Knoppix live Linux-on-CD can do this; it has a program called Partition Image that can create a drive image file and QTPartEd to manipulate partitions. It's free, of course.

Another tip: hard drive manufacturers often provide free cloning software so you can transfer data to your "new" drive. Check their web sites for downloads. I know that Maxtor and Western Digital have this.

It's a CD-burning program, primarily for audio CDs -- "CD-R disc-at-once".

I'm sorry, my original answer was based on a mis-read of your question (my eyes must have been on sideways that night)... Tekmaven is right, BlindWrite and CloneCD are the answers for most situations. There may be others, including free.
