I barely remember that Hitachi? Toshina? made a big hard disk that needs
helium inside the drive.

I consider such a design to be truly miraculous,
as you know how hard it is to keep helium
gas in anything. Helium gas is used specifically
for lab testing, for the detection and removal
of leaks in vacuum systems. It's a bitch to
keep it from leaking.


The seal should be pretty tight, I hope.

The Hitachi He6 was the first. It took quite a while,
from the first paper launch, until regular users
could find these for sale.

The cover on it, is rather plain looking. You would think there
would be a big gas spigot on the side, so you can refill it :-)

In this picture, have a look at the head stack. Impressive.
Use the zoom, to get a good look. The other detail which
is rather interesting - almost zero clearance between the
platter and the HDA. And the design doesn't look like it went
overboard in trying to keep the gas inside either. Notice how
the HDA has all those screw holes, and yet the "lid" in the
Newegg picture, shows no screw heads. I almost want to buy
one now, and take it apart :-)

Looks like about 6 or 7 heads! and about 7 screw holes alright and no
screws!!!!
Something queer going on, Maybe photoshopped? Gotta find more images
from somewhere and see whats up Doc.

Where I live, a dollar store sells helium baloons for a dollar.

I see people buy 5 at a time. It's terrible and such a waste. You
can learn all you need to know from one balloon.


What if you want to learn what you can do with five helium
balloons at once?

There should be a 3000% excise tax on helium.

No. Not really. Not all of them. It depends on the HDD manufacturing.
Some
models are durable, and some are not.

My 160GB WD only lasted about a year while my 3 years old 40GB Seagate is
still fine.


I have never had a dead hard disk, except that IBM Deathstar that used
glass platters. The other one I lost was a Seagate ST-251 40M (yes, 40M)
which was dropped accidentally.

FYI, my environment is somewhat harsh. No air conditioning (because
it's in
an open room), and the air is not clean enough.


Outside air shouldn't be able to reach inside the hard disk, but the
circuit board might be affected.


Outside air *does* reach the platter. There is a hole
in the cover, with a hepafilter fastened by adhesive,
on the inside surface.

http://www.howtogeek.com/127433/what...n-hard-drives/

This is a datasheet for a filter disc for the HDA cover.
Just to illustrate they do exist.

I used to work for a company that built both the pumps and the eqpt
that needed and used UHV (Ultra High Vacuum, 10^9 Tor). They had
high-end vacuum seals down pat. They had a number of test and demo
units that had been running for long periods of time (years), and it
was said one had reached a total vacuum.

There should be a lower tax, if there is a lawn chair
tied to the balloons.

So the top is welded on.

That'll make it a bit more difficult
to get the magnets later.

Torx driver is a nogo, here come the hacksaw, actually I have enough
sets of magnets already and with SSDs I won't be buying any HE6s anyway.

It should be easier than keeping HYDROGEN in. Or antimatter :-)
