You have to be carefull with the MBR, it's neighbor is the partition
table for the drive. If overwriting both on the other drives you'll have
issues.

Also grub is dependant on several factors when copying drives, mbr's,
installs. Your menu.lst or grub.conf needs to reflect the correct
partitions. And your /etc/fstab needs to be correct, at least as far as /
and /boot are concerned.

Some older motherboards have configurations for the harddrive they are
expecting to be using. Sometimes the default/auto assume only UDMA drives
will be used and if you plug an ATA drive in there, you'll need to tinker
in the CMOS/BIOS to get things comfortable again. In this case it doesn't
read the MBR because it basically doesn't see the drive. Even if it's
setup, jumpered, and plugged in right. This is more of a bios thing, you
may still be able to boot a liveCD and mount the drive and tinker just
fine, but just can't boot from it's mbr, until you change the bios
configuration.
