About the Product Capacity Representation Standard
About HDD Capacity Representation
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

smaller than the actual capacity due to the difference in capacity calculation.
(E.g. For a 80GB HDD, Windows represents the capacity as 74.5GB, 80x1,000x1,000x1,000

In addition, the capacity representation in Windows may be even smaller because some
programs such as Recovery Solution 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.
