Aha! I have erred! High time it was. All those numbers and me, and no 
error, highly unlikely.

[60]> (/ (let ((hddarea (* 1016L-1 +millimetre+ 146L0 +millimetre+)) 
(units1TB (* 10L0 8 +billion+)) ) (* units1TB hddarea)) 1L6)

1186.688L0

So, if we lay the harddrives one by another, like we usually put them into 
computers (i.e. flat), they would cover 1186 square kilometers. 
Unbelievable. I wonder if I made it this time :-).
