There is an explanation why space is missing. It is all about calculations (Apparent Vs. Actual). Drives are marketed in terms of decimal. So, 1 TB is in decimal, i.e. 1,000,000,000,000B while OS shows memory in terms of binary. Therefore, 1 TB is actually 931.32 GB (1,000,000,000,000/230). I personally use a 1 TB HDD and a total space of 931 GB is justified. So, the space isn't missing but the awareness of the facts.
