Quick answer
Manufacturers use decimal units (1 GB = 1,000 MB) while operating systems often use binary (1 GiB = 1,024 MiB), which is why a 1 TB drive shows as 931 GB.

Frequently asked questions
Why does my 1 TB drive show 931 GB?
The manufacturer counts 1 TB as 10¹² bytes; Windows divides by 1,024 three times, which gives 931 GiB of the same space.
What is a GiB?
A gibibyte — the IEC binary unit of 1,073,741,824 bytes, distinct from the decimal gigabyte.
