Updating the Encryption Key
You can update the encryption key. Applying the new encryption key takes the same amount of time as that for starting encryption. Updates are possible when the machine is working normally.
The machine cannot be used while the encryption key is being updated.
The encryption key is required for recovery if the machine malfunctions. Be sure to store the encryption key safely for retrieving backup data.
When the encryption key is updated, encryption is performed using the new key. After completing the procedure on the machine's control panel, turn off the main power and restart the machine to enable the new settings. Restarting can be slow when there is data to be carried over to the hard disk.
Once the updating of the encryption key starts, it cannot be stopped. Make sure that the machine's main power is not turned off while the encryption process is in progress. If the machine's main power is turned off while the encryption process is in progress, the hard disk will be damaged and all data on it will be unusable.
If the encryption key update was not completed, the created encryption key will not be valid.
