ARG!!! Don't do this! You really, really don't want to dd a raw disk
image (including mbr/partition table) to a *different* geometry disk -- it
does not matter what the 'disk' tech is (IDE. SCSI, SATA, SSD, etc.).
Partition the new disk with fdisk (or something like that), then use
mkfs to make the file systems than use dump/restore to move the file
systems. Finally use grub-install (or lilo) to install the boot loader.
