or

. Use

Full

format

to completely clean the disk. This may be necessary

if you give your device to someone else and you want to
erase all the personal data first. Use

Full format

also if

you have disk corruption problems. If corrupted sectors are
found,

Full format

will isolate those sectors to prevent

further problems. Use

Quick format

for a previously

formatted disk just to quickly erase the content.

Formatting is not a 100% safe way to destroy confidential
data. Standard formatting only marks the formatted area
as available space and deletes the address to find the files
again. The recovery of formatted or even overwritten data
may still be possible with special recovery tools and
software.

Digital rights management technologies may prevent some
back-up data from being restored. Contact your service
provider for more information about DRM used for your
content.

Digital rights management (DRM) protected content
comes with an associated activation key that defines your
rights to use the content.

If your device has WMDRM protected content both the
activation keys and the content will be lost if the device
memory is formatted. You may also lose the activation
keys and the content in case the files on your device get
corrupted. Losing the activation keys or the content may
limit your ability to use the same content on your device
again. For more information, contact your service provider.

If your device has OMA DRM protected content, the only
way to back up both the activation keys and the content
is to use the backup feature of Nokia PC Suite. Other
transfer methods may not transfer the activation keys
which need to be restored with the content for you to be
able to continue the use of OMA DRM protected content
after the device memory is formatted. You may also need
to restore the activation keys in case the files on your
device get corrupted.
