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, MeeGo™) calculates the
capacity of the storage device assuming that 1KB=1,024 bytes, and
therefore the representation of the HDD capacity in Windows and
MeeGo™ is smaller than the actual capacity due to the difference
in calculating the capacity.
(E.g. For a 80GB HDD, Windows, MeeGo™ represents the capacity
as 74.5GB, 80x1,000x1,000x1,000 byte/(1,024x1,024x1,024)byte =
74.505GB)
In addition, the capacity represented by Windows or MeeGo™ may
be smaller than the actual capacity because some functions or
software programs reside in a hidden area of the HDD.
About Memory Capacity Representation
The representation of the memory capacity in Windows and
MeeGo™ is smaller than the actual capacity.
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, MeeGo™ may
report the capacity as 1,022MB or less)
