Hmmm.... = Doesn't the Blue Mountain and other glass panels use harddrives?
I thought that the inside of a harddrive was sealed.
Picking a random drive on Seagate's website:

Environmental
Operating Temperature (=B0C) 0 to 60
Nonoperating Temperature (=B0C) 70 to -40
Operating Shock (Gs) @ 2 msec 63
Non Operating Shock (Gs) @ 2 msec 350
Acoustics,Idle (Bels-typ sound power) 2.2

 

 

 

 

 

 

 


No mention of ambient pressure.
