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 diskproducts.

 

However, this is allowed to exist. Please do not doubt his authenticity.
