Saving Data on the Hard Disk
Hard Disk Lock
When the Hard Disk Lock is set to [Enable], it is impossible to read/write data from/to the hard
disk when the hard disk is installed in a different computer, since a password is also set for the
hard disk. When the hard disk is returned to the original computer, you can read and write data as
before. In this case, however, make the settings in the Setup Utility exactly the same as they were
before the hard disk was removed. (Note that this Hard Disk Lock does not guarantee the com-
plete protection of data.) ( “Security Measures”)
Do not expose your computer to shock.
Use care when handling your computer, shock may damage your hard disk or make your
software applications and data unusable.
Do not power off your computer while software applications are running or hard disk
drive indicator is on.
Properly shut Windows down to avoid problems.
Save all valuable data to disks, etc.
Backing up data to disks, etc. will limit damage should trouble occur to your computer or
should you inadvertently change or erase data.
Use the security function for all important data. ( “Security Measures” and
“SD Memory Card Security Function”)
When Using Peripheral Devices
Pay strict attention to the following points to avoid damage to the computer, peripheral devices,
cables, etc. Also, in addition to following this manual and the Reference Manual, carefully read
the instruction manuals for the peripheral devices being used.
Use only peripheral devices that conform to the computer’s specifications.
Connect the devices properly, paying close attention to the condition and position of the
connectors.
If a connection cannot be made easily, do not apply undue force; check once more to con-
firm the condition and position of the connector (alignment of pins, etc.).
If the connector has holding screws, fasten the screws firmly.
Do not carry the computer with cables attached, and do not pull on the cables forcefully.
Users are advised to purchase the latest versions of virus protection software and use
them regularly.
We recommend you run the software:
• When booting your computer.
• After receiving data.
We recommend that you check data received on disks or from external sources, such as data
downloaded from the Internet, e-mail, etc. (For compressed files, uncompress them before
running a check).
For Data Execution Prevention (DEP), you can make one of the settings in the following menu.
[start] - [Control panel] - [Performance and Maintenance] - [System] - [Advanced] - [Settings]
(in [Performance]) - [Data Execution Prevention].
