Yes, it is possible, but would it help?
If your drive fails, then you loose the data anyway.
I guess this would protect against bad sectors in one part of the
drive, but my experience is that once you get a bad sector or two your
drive isn't long for this world.
Also, write speed would be appalling as the head would be zipping back
and forth between the two partitions.
However, the best answer is "try it", and see if it does what you
want.
