If possible, it is no doubt classified. I remember hearing rumors around 20 years ago about how Russian spys could read a Magnetic Disk drive from outside a building. I think it had something to do with RF frequencies and/or noise bleeding around. Don't know how you could write on a magnetic disk drive remotely. But man the problems that could cause. Yikes.

Fairy tales for sure:). One friend once worked into the so called “post box”. It is the jargon nick for secret research intitute. He told that they had there the metallic net inserted into glass of thier windows! It is for shielding any radio band. Not mention those windows were tri-packed and had special rough covering to refuse the laser reflection. To read the data from thier disks one can if he was been doing the reading sitting before display in thier display room. From outside it was impossible ever. Not mentioning thier computers were not connected to no network. And thier displays has no writing devices in it.
“think it had something to do with RF frequencies and/or noise bleeding around.”
Very perceptive. That is why DOD computer rooms have shielding.
