If you have smartmontools installed, you can check:

smartctl -a /dev/whatever

Create a partition at least 1MB in size with no filesystem on it.
(unformatted is the last choice in gparted) Give it a flag of bios_grub in
gparted or type ef02 in gdisk. When it comes to grub-install, grub will
know what to do with it.

Some howtos say it must be the first partition. I haven't found that to be
true. I've put it in the middle and at the end. It works.
