Common pitfalls and look-alike units
This page uses SI decimal units: 1 KB = 1000 B. Binary contexts use KiB (1 KiB = 1024 B). Drive makers label in decimal while operating systems often display binary, which is why a 500 GB drive shows about 465 GiB — expected, not a defect.
Frequently asked questions
