What 1TB Actually Holds
1 TB = 1,000 GB = 1,000,000 MB

Why Your 1TB Drive Shows 931 GB
Drive manufacturers use decimal (1 TB = 1,000,000,000,000 bytes), but your operating system uses binary (1 TB = 1,099,511,627,776 bytes). The difference means a "1TB" drive shows approximately 931 GB in your file manager. You are not missing any storage โ it is just a measurement discrepancy.
