perform basic maintenance tasks such as
defragmenting and scanning for errors with your
compatible PC, as well as other hard drive
maintenance and troubleshooting.
NOTE: Before doing any maintenance
back up your hard drive data to a
compatible computer.
Backing up and restoring data
There are four different ways to back up your data
•Device memory: Use Nokia PC Suite (this is especially
important if you have digital rights management
(DRM) protected content)
•Hard drive data: Using compatible PC and File
Manager (Select Mass Storage mode and drag and
drop your device hard drive contents to your
compatible PC)
•Hard drive data: Using Apple Macintosh (Select Mass
Storage mode and drag and drop your device hard
drive contents on to, for example, your Mac desktop)
•Music on hard drive: If you want to back up only your
music, you may also use Windows Media Player and
sunchronize the music.
When the hard drive is formatted, all data on the
drive is permanently lost. Back up data you want to
keep before formatting the hard drive. You can use
Nokia PC Suite to back up data to a compatible PC. If
your device needs to be repaired or replaced, a
backup copy is required to restore data protected
by digital rights management technologies (DRM).
Digital rights management technologies may
prevent some backup data from being restored.
Contact your service provider for more information
about the DRM used for your content.
NOTE: In case your device is swapped,
completely erased, or you have no copy
of your License rights, it is
recommended keep a list of all the
purchased DRM protected content that
you have. A copy of, for example, your
credit card invoice is good proof of
purchase in case you need to ask for
your licenses back from the content
provider.

TIPs to enhance the performance of your Nokia device
TIP1: Do not set the hard drive as your "memory in
use" for messaging (SMS, MMS). This affects
messaging performance and battery life.
TIP 2:
Q: I turned my device off for charging and now my
personal wallpaper/theme is no longer on the display.
What has happened?
A: This may happen if you store your wallpaper on the
hard drive of your N91. Use the device’s memory to
store wallpapers.
TIP 3: For optimal application performance, install
applications and games in the device’s memory
instead of on the hard drive if possible .
TIP 4: If you receive an "Out of Memory" message
when using some applications (for example, Web
Browser) this is not related to the hard drive, but to
the device’s RAM. Ensure all applications not in use are
closed.
TIP 5: If an application will not install or run on the
hard drive remember it is an S60 third edition device,
so old .SIS files may not work. Before you download/
buy and application, make sure that the application is
compatible with an S60 third edition. You should also
verify that it is made for the N91 as well to be sure.
TIP 6: It may appear that the hard drive is running
slowly when opening Gallery for the first time after
loading a huge amount of content onto the hard
drive or replacing the battery. Subsequent gallery
access should be faster.
TIP 7:
