[comp.sys.mac.hardware] Quantum Fix. Arm Or Platter sticktion

	Evening Peoples.

I have been working on quantum drives for 3 years. So i consider myself
fairly well up to date on them. but for a change i've been confused.

Quantum released a series of drives with server locking problems
with the platter drive assembly, also rodime and a few seagates had this
problem. The result was the drive doing nothing appart from chattering
and then flashing the led, an indication the onboard computer detecting 
system failure.

	The replacement of the bearing rings and a gas recharge gave these
drives a decent span of extended life, but lately people have been talking
about the armature sticking. I have never come across bad bearing rings in the 
voice coil driven access system. 


 The question i ask is, has anyone, who is informed or works on quantum drives
ever come across this fault. As i have never. if you have, what was your
remedy?

quite curious actually!


thanks in advance
