replacing failing system disk

[Shea Martin <sheam@ns.sympatico.ca>]

My hda is going south. I have a good (crosses fingers) disk as /dev/hdb
right now.  My plan for migration is this:

1. fdisk /dev/hdb, and create similar partion scheme on hdb.
2. newfs all new partititions, mkswap on swap partition.
2. from knoppix, "cp -a" the contents of /dev/hda to /dev/hdb.
3. chroot to the / of hdb, and run grub.
4. poweroff, pull hda, make hdb the new primary-master (aka hda).
5. boot and pray.

Anyone see any wholes in this theory?

Thanks.
