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 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)
Safety Precautions

Cautions on Preventing Data Loss
(Hard Disk Management)
Take care not to damage the data on a hard disk drive.
A hard disk drive is so sensitive to external impact that an
external impact may cause loss of data on the surface of the
disk.
Take extra care, because moving the computer or an impact
on the computer when it is turned on may damage the data
of the hard disk drive.
The company is not liable for any loss of any data caused
by a customer’s careless usage or bad environmental
conditions.
Causes that may damage the data of a hard disk drive and the
hard disk drive itself.
The data may be lost when an external impact is applied to
the disk while disassembling or assembling the computer.
The data may be lost when the computer is turned off
or reset by a power failure while the hard disk drive is
operating.
The data may be lost and irrecoverable due to a computer
virus infection.
The data may be lost if the power is turned off while running
a program.
Moving or causing an impact to the computer while the hard
disk drive is operating, may cause les to be corrupted or
bad sectors on the hard disk.
To prevent data loss due to damage to the hard disk drive,
please backup your data frequently.
