You have discovered my greatest hatred against Rodime.  Your suspicion of
the 'kur-chunk' is very correct.  An EX Crudime (as I call them) engineer
explained it to me.  The Rodime has a speed circuit like a hair trigger.
If it detects that the platter speed is too unreliable it panics, and pulls
the heads off.  A few microseconds later, it decides that everything is
hunky dorey and puts them back out there.  It usually starts happening
after the one year warranty has expired.  It will grow until it gets to the
point that it will do this about every 5 to 10 secs.  At that point the
drive is no longer usable.

"I have never seen a Rodime drive that worked after one year"
- yours may be the first

Again, I'm sure there is one (maybe two) happy rodime users who will
disagree, but that's why it is IMHO.
