Why 1TB Hard Drives Show as 931 GB in Windows

Storage manufacturers use the decimal system (1 KB = 1,000 bytes, 1 TB = 1,000,000,000,000 bytes). However, computer operating systems like Microsoft Windows count memory using the binary system (1 KiB = 1,024 bytes).

1,000,000,000,000 ÷ (1,024 × 1,024 × 1,024 × 1,024) ≈ 0.909 TiB (or ~931.32 GiB displayed as "GB" in Windows). Your drive is not missing space; it is simply formatted using binary base-1024 math!
