Neither, this is actually a misperception of what a Gb really is. A Gb is
_not_ 1000Mb, despite what harddrive manufacturers will gladly tell you,
it is 1024Mb, and a Mb is really 1024Kb, and so on.
Taking a look at your particular case, 90,000 Mb divided by 1024 (not
1000, so it isn't 90) to get Gbs is 87.89G, which is indeed exactly what
you have, no?
