also imitate RAID1

I’ve always thought that there should be a jumper on disks to div. the capacity

for single platter: write the same data on both sides of the platter

for two platter: write the same data on both platters

for the three & five platter oddballs: write the tops as one cylinder and the bottoms as the mirror cylinder

eg.

  • a 500GB with 2 platters would become a 250GB in Mirror on the platters

  • a 2TB with 4 platters would become a 1TB

this could be used to support those with older OS which don’t go above 2TB

thus a new 3TB disk with “mirror” jumper would become a 1.5TB

and when they push 4TB disks add the jumper and voila a 2TB with internal data mirror
