Re-index Media Files
Multimedia data within the installed applications can be scanned and re-indexed for applications. Click Re-
index to re-construct the index structure of all media files in the indexed folders, both default folders and the ones
created by you. The process will be executed in the background.
Reset Admin Password
If you forgot the password for admin and are therefore unable to log in to DSM, you can reset the password to
blank and set a new password.
To reset admin's password:
Press and hold the RESET button on the back panel of your Synology DiskStation for 4 seconds until you heard
a beep sound.
Note: Other than resetting administrator's password, using the RESET button will also restore Synology DiskStation's
IP and DNS to the default value.
Restore Synology DiskStation to Factory Defaults
Go to Main Menu > Control Panel > Restore Defaults if you want to restore your Synology DiskStation to
factory defaults.
There are three restore options:
 Format the hard disk but keep the current settings: All user data in the hard drive will be deleted; whereas
the system configurations will remain.
 Format the hard disk and restore to factory default settings: All user data in the hard drive will be deleted
and the entire system will be restored to default.
 Reset MySQL Database Password: The password of the MySQL database will be reset.
If you wish to delete your MySQL databases, check the Delete MySQL Databases checkbox and click Apply.
