Advanced Settings
Maintenance (Initialization)
Initialization is a reset procedure that
restores all settings back to the default, out
of box, configuration. All configuration,
users, groups, and backup jobs are lost,
but actual data and shares on the hard are
NOT lost. If you want all data to be erased,
reformat the drive.
Specify whether the LinkStation shall
keep its administrator password after a
initialization or whether the password
should be reset to the default password
(default password is password). Press the Apply button once you make the selection.
Press the Restore button to begin the initialization process; this will restore all settings to factory
defaults but will NOT erase the data on the hard drives.
