Hi Folks,

The concept of recovering data from RAM is based on "residual memory" of the medium (the actual RAM strips), so we are into the realms of electron tunneling scanning microscopy.

I hope the link is up. It is Peter Gutmann's site and he goes into this kind of stuff way over my head (not difficult )

I guess you will have heard of the "Gutmann method" of secure deletion? the guy is a guru when it comes to these kind of security issues.

I guess it is not too far fetched, as I can remember the old IBM 5256 dumb terminals that had been used for order entry, invoice posting and such in the Finance Department. In the right light you could read the permanent header texts that had been burned into the screen by the electron guns in the CRT.

Cheers

EDIT: Just checked the link and it is working now. CXGJ I am sure you will find the site interesting..............he describes himself as a "professional paranoid"..........taught me almost all I know
