Decimal (1,000) vs. Binary (1,024) Data Units

Ever wonder why your brand-new 1 TB hard drive shows up in Windows with only 931 GB of usable space? It comes down to decimal vs. binary arithmetic:

Hard Drive Manufacturers (Decimal): 1 TB = 1,000,000,000,000 Bytes (10¹²).
Operating Systems (Binary): 1 TiB = 1,024 × 1,024 × 1,024 × 1,024 = 1,099,511,627,776 Bytes (2⁴⁰).

1,000,000,000,000 ÷ 1,073,741,824 ≈ 931.32 GiB. Your drive is not missing space—it is simply reported using binary Gibibytes!
