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 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.
