Hard drive maintenance
The purpose of this document is to help you to 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
synchronize 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.

Question
What should I do if the hard disk on my Nokia device makes
unusual noises?
Answer
If the drive is making any loud, unusual noises such as
clicking or grinding, the drive may be about to fail and may
need to be replaced. Back up any sensitive data you want to
keep while the drive is still operable.
To do this, connect your Nokia device to a compatible PC
using either a USB cable or Bluetooth technology. If you are
using the DKE-2 USB cable, select USB as the connection
method. This method gives you total control of what
you move and to where, but you cannot see all the file
information. You may not be able to transfer material that
has been protected against copying. Additionally, use Nokia
PC Suite to back up the data in the device’s memory, in case
the device is replaced.
If the hard drive fails or if the noises persist, contact your
nearest Authorized Service Center.
Question
What can I do if my Nokia device does not detect its own
hard drive?
Answer
You may have run into a hardware problem.
If the hard drive is not recognized by the operating system or
any device applications, there are a few things you may try
out before contacting the nearest Authorized Service Center.
Try connecting your Nokia device to your compatible PC and
run disk utilities. If the connection cannot be made (in other
words, your PC does not recognize your Nokia device hard
drive) then try to pdate your Nokia device software using
Nokia Software updater, which can be found at http://europe.
nokia.com/ under the support section. If updating the
software is successful, format your Nokia device hard drive.

TIPs to enhance the performance of your Nokia device
Copyright © 2006 Nokia. All rights reserved.
TIPs to enhance the performance of your
Nokia device
TIP 1: 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 an 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: Avoid interrupting the installation of programs on
start up.
TIP 7: 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 8:
Q: What can I do with my hard drive to prepare for a SW
update?
A: If you are planning a SW update (with new or the same
SW version). Note the following recommendations before
proceeding:
Backup your device’s memory using Nokia PC suite (to
preserve your DRM activation keys, etc).
Copy your files (Music, Videos, Documents, Images
etc) from the device’s hard drive to a compatible PC
(recommended to use USB Mass storage mode).
