Hard drive manufacturers is 1000 hex, WINDOWS is 1024 decimal, so the actual capacity may be tolerance.
For example: 1MB=1000KB, 1G=1000MB calculated, but the operating system is using binary arithmetic: 1MB=1024KB, 1GB=1024MB. So there are some differences between display capacity and nominal capacity of hard disk/flash memory products.
However, this is allowed to exist. Please do not doubt his authenticity.
