	Brent, you have a problem. I have been repairing rodime drives at
surface level for a year now, and have found, well what i have concluded to find
is that the rodime is resetting. After having my programmer disassemble their
on board MPU ROM. i found that it will reset uner certain conditions, one of    
them appears to be the temp of the current transfer HIC driver, and the other
being CLV error report. (The Constant Linear Velocity IC reports a failure 
if for some reason the spped of the disk alters, or it strays from a certain
reference track. We are still in the process of accumulating a data base on the
rodime (Before cobra) range. the drive is repairable (easily), but involves
heay testing before ensure the fix has solved the intermitten parking problem.
During a reset it is considered parked, so it releases the solenoid and the
spring within the drives forces a park situation.

PS my keyboard is dying, Sorry about the errors, I have a Hammer tied to the    
keyboard via a piece of string (for those extra hard to get keys)
