Motion LS800 table HD failure at 14,000 feet

You may want to check with a computer hardware group, but
here are my comments.

Hard drives fly the read/write head on the air cushion over
the platters. As the air gets thinner at altitude, the head
crashes.

You may be able to find hardware rated for altitudes up to
FL180 or even higher. You can contact the hard drive and
laptop makers to see what options they have.

You have found why avionics cost more than consumer grade
and budget computers.

Try Google and search for key words.

I found a

NT4 though.

Oh please... This is an issue of mission profile, not FAA certification.
