He is now in some trouble (I hope a *lot* of trouble, if the allegations
are true).

BTW, the newscasters were not nice enough to show us some of those

CHP = California Highway Patrol, same as State Police in some states.

What isn't
recommended, is opening the drive in your dusty
living room, with absolutely no advanced preparation.
Even if you take the drive into a cabinet, you should
clean the outside of it a bit first, before opening it
up.
I haven't done it in a long time, but I once opened a 170MB drive -
yes, a looong time ago - and blew compressed air on the platters, as
there was a small piece of plastic or two floating around there giving
fake read errors when they hit the heads. Anyways, this was all done
"in my dusty living room" and I had no issues afterwards :-)

"How to Make a Clean Air Enclosure (for HDD repair etc)"
That was impressive - thanks.

Yeah, that's the same glove box design they
use for working on Ebola samples.

Are they also made up of cardboard and duct tape?

Rather than putting that cardboard box under negative
pressure, the hepafilter could be providing positive
pressure on the source end. That causes air leakage to
move out of the box, through whatever "gaps" exist
around the "gloves" area. Then you can leave the fan running
while you work.

As long as you are pumping clean air in. But yes, I agree.

Someone on the news or in a magazine article recently spoke of keeping a
biological isolation chamber under negative pressure and called doing
that "counterintuitive". Oh well.


Ebola, I'd keep that under negative pressure, pulling the
gloves inside the glove box. I wouldn't want any biologicals
blowing out through cracks in the box. And you want your
vacuum cleaner to vent... outdoors.

Or through a tank of chlorine bleach...

Although ebola, specifically, might not be a problem, if it really can't
be transmitted through the air. If...

But for the hard drive, I'd want positive pressure. Especially
as the "glove port" isn't really sealed at all. if you're making
it out of cardboard, might as well be positive pressure, considering
the level of leakage.

That's why I said "I agree".

Still, Matt's clean room is probably still much better than any room in
my house :-)
