About Capacity:
hard disk vendors are using decimal arithmetic: 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 products.
However, this is allowed to exist. Please do not doubt his authenticity.
