There is a procedure for erasing stuff like this - it can be found in (at
least) older Xicor books. It generally involves writing and erasing
patterns and zeros to the memory quite a great deal (thus, used EEPROMs
from the military should be suspect, as they could be worn out).

Ignored, or overreacted (just like the shovels a buddy had to break the
handles off of, just because their part number showed them to be included
in an antenna guy kit that required demilling).

Yes, government machines are often missing drives.
