              ^^^^^^^^^

What?!? 16 exabytes?! That's what? 16 * 10^18? Are you joking? All the 
disks on earth wouldn't add up to that capacity. (Well, maybe they would 
in these days of cheap 100GB disks, but it's a close thing :-).

It's simply reporting the 18446744072770031616 number in a compact 
format. The internal *value* is wrong, because it's doing an incorrect 
32->64 bit conversion somewhere, but the format doesn't make the result 
correct.
