Operation
zUse the security function for all important data. (⇒ Reference Manual “Security 
Measures”)
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/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 complete protection of data.) (⇒ Reference 
Manual “Security Measures”)
zDo not power down your computer or press the floppy disk drive eject button 
while the MP indicator   is on.
Doing so may damage the data on the floppy disk and render the floppy disk use-
less.
zUse care when handling floppy disks.
To protect the data on your floppy disks or to prevent a floppy disk from becoming 
stuck in your computer, avoid the following:
 Sliding the shutter on the floppy disk manually. 
 Exposing the floppy disk to a magnetic field.
 Storing the floppy disk in locations prone to high temperatures, low pitched noise, 
dampness, or dust.
 Applying more than one label on the floppy disk.
zConfirm the contents of a floppy disk before formatting it.
Confirm that no important data is on the floppy disk, because all data on the floppy 
disk will be erased.
zUse the write-protect tab (A).
This is a must for preserving important data.
This prevents your data from being erased or overwritten.
zWhen disposing of or transferring ownership of this device, erase all data on the 
hard disk in order to prevent the theft of hard disk data. Even if you delete data or 
initialize the hard disk through normal Windows commands, data can still be read 
using special software. In order to erase all data, either have the data erased by a 
specialist (at a charge) or use the hard disk data erase utility (included) ( Îpage 
34).  (Note that this hard disk data erase utility does not guarantee that data will be 
completely erased.)
Also, note that if you transfer ownership of this device without deleting commercial 
software that you have installed to the hard disk, you may be in violation of the 
licensing agreement for that software.

Troubleshooting
Cannot start a network-used 
program, or cannot share 
files or printerszIf you cannot start up a program or share files, this may be because the “Firewall 
(Windows Firewall)” in the “Windows Security Center” is set to be enabled.
If this function is set to be enabled, damage from viruses and other attacks is 
reduced, but some programs and functions cannot be operated.
To use the program or to share files or printers:
You can use programs or other functions without the effects of the Windows Fire-
wall by registering them as an exception in the Windows Firewall settings (it is not 
necessary to disable the Windows Firewall).
Note, however, that if a program is registered as an exception, there is a risk of 
damage from viruses or other attacks.  Before registering a program as an 
exception, confirm the program’s safety with the manufacturer or other reliable 
source.
ASelect [start] - [Control Panel] - [Security Center] - [Windows Firewall].
BSelect [Exceptions].
CTo register a network game or other programs as an exception:
Select [Add Program], select the program, and select [OK].
To set access through a specified port as an exception:
Select [Add Port], set the port, and select [OK].
To set a file or printer as an exception:
Add the check mark for [File and Printer Sharing].
DConfirm that there is a check mark for the item to be set as an exception, 
and select [OK].
Is it necessary to enable the 
Windows Firewall?zThe Windows Firewall is a security function designed to protect your computer from 
unauthorized access via the Internet and other external networks.
The firewall regulates the data exchanged between the computer and the external 
network, so that only approved data can pass through. We recommend that you 
use your computer with the Firewall enabled to minimize damage from viruses and 
other malicious attacks.
zWhen installing additional commercially available firewall software, we recommend 
that you disable the Windows Firewall settings, as the new software may interfere 
with the Windows Firewall functions.
For details, refer to the manual accompanying the firewall software to be installed.
When “Automatic Updates” 
is enabled, will all updates 
be downloaded (or 
installed)?zOnly Windows Update programs with a high level of priority will be automatically 
downloaded (or installed).  
Update programs with a comparatively low level of importance will not be down-
loaded (or installed) automatically. Check regularly whether new update programs 
have become available.
Security Center warning 
function does not operatezThe Security Center warning function will not operate if you are using a network 
domain, for example at a company.

Problem with Web page 
display (no display; display 
is completely white; 
advertisements, logon, and 
other pop-ups are not 
displayed)zIn Windows XP, security functions have been strengthened with regard to Web con-
tents.
One of these is the “Pop-up Blocker,” which may prevent some Web pages from 
being displayed.
If you have any problems with Web page displays (e.g., if a page cannot be dis-
played correctly on Internet Explorer), check the contents of the message window 
displayed below the address bar (called the “Information Bar”). The Information Bar 
shows the information that has been suppressed by Internet Explorer.
 If the message “Pop-up blocked” is displayed:
Select the message, and select “Temporarily Allow Pop-ups.”
The blocked Popup will be displayed temporarily.
 If the message “This site might require the following ActiveX control...” is dis-
played:
ASelect the message, and select “Install ActiveX Control.”
BCheck Name and “Publisher” on the [Security Warning] screen, and 
execute the installation.
 If you cannot find the Information Bar:
If you need to display the page, select the Web page link while pressing 
Ctrl. 
The pop-up blocker function will be temporarily disabled.
Images in HTML e-mail 
messages are not displayed 
in Outlook ExpresszIn Windows XP, there is a function that blocks image displays in HTML e-mail mes-
sages.
To display images in HTML e-mail messages, it is necessary to access the 
sender’s server, and this may cause problems in the computer.
Preventing these images from appearing can decrease the risk of attack from 
viruses etc.
If you need to display images, select the segment where the message “Some pic-
tures have been blocked…” is displayed.  The images can be displayed temporarily.
Cannot read attachment file 
in Outlook Express (cannot 
save file)zIf a message received in Outlook Express has contained an attachment file with an 
extension such as “.exe or “.scr” (potentially unsafe files), Windows XP blocks 
those files.
If you need to read the files, select [Tools] - [Options] - [Security] and remove the 
check mark from [Do not allow attachments to be saved or opened that could 
potentially be a virus].

Troubleshooting
The message “Your 
computer might be at risk” is 
displayedzThis message is displayed by the “Security Center” function in Windows XP.
The “Security Center” is a function that monitors the level of safety in Windows 
security settings in order to operate the computer safely, for example, with regard to 
antivirus measures.
It checks the following three items regularly, and displays messages until the set-
tings are made at an appropriate level of safety.
 Firewall: Is the Windows Firewall enabled?
 Automatic Updates: Is the automatic Windows Update function enabled?
 Virus Protection: Has antivirus software been installed, has the latest version of 
the antivirus software been installed, and is the real-time search function enabled 
(ON)?
zThe message “Your computer might be at risk” is displayed by the “Security Center” 
function, and does not indicate an error or malfunction.  The “Security Center” func-
tion checks the above three items to ensure that your computer can be used safely, 
and notifies the user if the settings are not at an appropriate level of safety.
