[rdibxavj] Single disk RAID

Divide a single hard drive into partitions and run RAID across them.  While this may seem silly, the point is to write data redundantly to the disk.  In the event of data loss due to not-very-serious damage in one of the partitions, the data may still be recovered using the error correction of RAID (at the appropriate level).

If the hard drive completely fails in one of its (unfortunate) many single points of failure, then you lose, though one should still be able to recover data off the platters, for a very high price.

Make many copies of the partition table.
