You see, when I click on the 2TB HD, it says:

"Capacity: 2TB
Available: 2TB
"

However, when I look at it in Finder, under SIZE, it says "852.6 MB"... why is this? Why the discrepancy?
 
And yet, when I click the HD, it appears to have no contents. What is taking up that (admittedly minor) amount of space, then? And why does it tell me the HD does has 2TB free when I request info on the drive?
 
Operating systems and working overheads.

And for why it still says "2TB": 2 TB - 834 MB = 1.999161 TB (SI)

i.e. it's correct to 3 decimal places which is still excessively accurate.
 
partition, boot, and trash information takes up space. Also humans think in powers of ten vs computers calculate in 2's.
