Grub stage 1 resides within 446 bytes of the MBR.
Grub stage 1.5 resides in the spae between the MBR and the first partition.
Grub stage 2 resides in the /boot within a partition.

It's entirely plausible that some of stage 1 and stage 1.5 may need changes.

In any case, the last upgrade I did tried to write in the space between
the MBR and the first partition of on of my hard drives.

I'd like it to stop trying that, letting it write to my other drives and
never boot from this one again, which I plan to remove when I find my
screwdriver.
