[comp.sys.mac] Chirping DataFrame

lewis@endor.harvard.edu (Harry Lewis) (11/13/86)

After five months of flawless service, 
my DataFrame disk has started to emit a painful high-pitched chirp/squeak.
I remember it being reported earlier that the cause of this problem was
an anti-static brush which was, in fact, unnecessary, and directions
were posted on how to open the case and retract the brush; but I
can't track those directions down.  Could someone send them to me, or
provide any other information on this problem?

	WHAT! anti-static brush unecessary???? I suggest that you do *not*
remove it.  Usually, those brushes are soldered in place. What you should do
is unsolder it to take the brush out, clean the contacts, and maybe put a
wee-dab of some semi-solid lubricant (I don't remember the type) on it.
Then resolder it back on.

Apparently several drive manufacters HAVE suggested that the anti-static
brushes are not necessary. In fact, a DataFrame representative said that
it was ok to remove the brush. According to him it was a holdover from 
older drives. Supposedly many newer drives don't incorporate this feature.
