Head crashes are always bad. What generally happens for 5" and 3.5" winis
is the head is ripped off the mount, slammed against the wall and shattered.
the free arm gouges the platter badly. the metal dust from the grinding
gets into the rest of the heads and it cascades. If shut down when the head
first goes the platter will be shot. Repair would be trying to get head
and arm assembly, another drive to get a good platter from. Then there
is the problem of disassembleing the platter drive assy as many are "glued
and screwed" and maintaining tolerances on assembly.
