one technique that works quickly and simply for *cloning* disks (i.e. you've got one disk that's already partitioned, has data on it, etc. and you've got another of the same make and model, and you want two exact copies) is to use dd. since it's a block-level operation, it couldn't care less about whatever sorts of filesystems you've put on the disk, it'll preserve the MBR and whatever bootloader you may have there, and so forth.
- install source disk and target disk in a machine (hooray for hot-
swap bays!) 2. boot from CD or from other disk (i.e. *not* the target disk) into single-user mode 3. dd if=/dev/sdb of=/dev/sdc bs=1024 (source disk is /dev/sdb, target is /dev/sdc)
I really don't recomend it. You will get all kinds of geometry related problems, not to mention it will take ages to copy.
From my experience, even with all the extra work you have to do copying each filesystem one by one, it is still faster (total time) and a wholedisk dd.
