After many years of using disks, all the way back to the old Bryant 2A with
3.5 FOOT platters (honest!), I believe that today, with the modern
technology, dropping a disk is the biggest cause of failure followed by
bearing wear. I have never had a disk fail that I could prove was due to
positioner problems or to the electronics failing. Cables can be a problem.
Power supplies don't seem to be a cause either.
