it is perhaps a combo of dust and fumes deposited on there... methyl Ethel
keytone... but then the cleaner will cause your liver to drop out of your
body an and is a really bad cancer thing.....
another thing that might be better is to take it to a clock shop where they
have some wonder solvents and a large ultra sonic cleaner....
let them breathe the various fumes.......
be careful with any of this stuff you use.....

Subject: HP 7906 drive lives again & stuff
After suffering a head crash on my "new"
7906, I decided I REALLY should
have taken the time to clean the filter and the blower squirrel cage and
air
ducts better before using it. That was done, then the
drive wouldn't seek
past load point. So I swapped all the cards in the drive card cage with a
"spares set" and now the drive is working wonderfully again, passing all
diags. It is SO nice to not rely on a single 7900 drive anymore!
Word to the wise - lesson learned - never skimp on dissassembly/cleanup of
an old style 14" drive. Take the time to get every last piece of dust &
debris out!
Over the next few weeks I will be cleaning, refurbing, and testing all the
other 7906 drives I have. Once I get all working that can be made to
work...
I will have some known working 7906 drives available
for trade, as well as
some 13037 controller boxes. Might not have spares of the 13037 pca that
goes in the host though. If anyone is interested, let me know. Keep in
mind
these drives are somewhere in the neighborhood of 200
pounds each. I may
get
my 7905's working too but not sure I want to give
those up just yet.
Also - the only way I found to clean the squirrel cage blower was to take
it
out and clean each fan blade by hand and with a
toothbrush. The very fine
dust that makes it past the secondary filter cakes on these blades and is
very hard to scrub off - it's like concrete. Does anyone have any ideas
here? I was thinking of soaking the blower in something to loosen the
dirt,
but it's unfinished metal and might rust. Any
thoughts?
Regards,
Jay West
