Frequently asked questions
Why are there two versions of GB — GB and GiB?+
It's a long-standing inconsistency in computing: storage manufacturers (hard drives, SSDs, flash drives) use decimal GB (1,000³ bytes), while operating systems traditionally reported binary GiB (1,024³ bytes) but often mislabeled it as "GB" — which is exactly why a "1 TB" drive shows up as roughly 931 GB in Windows. This tool includes both so you can convert either way correctly.
Why does my 1 TB drive show less than 1,000 GB in my operating system?+
Because the drive manufacturer used decimal TB (1,000,000,000,000 bytes) but your OS is displaying the binary equivalent, labeled GB but actually meaning GiB (1,024³ bytes) — 1 TB decimal equals about 931 GiB. Nothing is missing from your drive; it's a unit-labeling mismatch.
