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)

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.
When moving the product,
turn the power off and
separate all connected
cables rst.
The product might be
damaged or users may trip
over the cables.
For long periods of not
using the notebook
computer, discharge the
battery and preserve as it
is detached.
The battery will be
preserved at its best
condition.
Do not operate or watch
the computer while driving
a vehicle.
