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 that 1KB=1,024 Bytes, and therefore the capacity representation of the HDD in Windows is 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 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 Solution may reside in a hidden area of the HDD.
About Memory Capacity Representation
The memory capacity reported in Windows is lesser 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)
The actual capacity of storage device can be checked in the Main menu of the BIOS Setup, accessible by pressing F2 key during boot. For further instructions on how to enter the BIOS Setup, refer to "Settings and Upgrade" in the User Guide.
