About the Product Capacity Representation

Standard

About the capacity representation of the storage

The capacity of the storage device (HDD, SSD) of the manufacturer

is calculated assuming that 1KB=1,000 Bytes.

However, the operating system (Windows) calculates the storage

device capacity assuming that 1KB=1,024 Bytes, and therefore the

capacity representation of the HDD in Windows is smaller than the

actual capacity due to the dierence in capacity calculation.

(E.g. For a 80GB HDD, Windows represents the capacity as 74.5GB,

80x1,000x1,000x1,000 byte/(1,024x1,024x1,024)byte = 74.505GB)

In addition, the capacity representation in Windows may be even

smaller because some programs such as Recovery may reside in a

hidden area of the HDD.

About Memory Capacity Representation

The memory capacity reported in Windows is less than the actual

capacity of memory.

This is because BIOS or a video adapter uses a portion of memory

or claims it for further use.

(E.g. For 1GB(=1,024MB) memory installed, Windows may report

the capacity as 1,022MB or less)
