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)
