After more than a year of use I was shocked discovering that my 4TB WDC_WD40EFAX-68JH4N0 only gave 3221GB worth of free space. Why is the user capacity only 3.22TB? Where are the other 700Gigs of space? Desperately seeking for more free space, can someone explain if the original format maybe was done wrong and how to get more space out of this 4TB drive?

∆ this is what puzzled me. Only 3TB?
