Use the following procedure to cancel the encryption settings when encryption is no longer necessary. Enabling and disabling the encryption settings takes equally long.
The machine cannot be used while data encryption is being cancelled.
After completing this 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 canceling of data encryption 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.
When disposing of a machine, completely erase the memory. For details about erasing all the memory, see Deleting Data on the Machine.
Log in as the machine administrator from the control panel.
Press [System Settings].
Press [Administrator Tools].
Press [Next] 3 times.
Press [Machine Data Encryption Settings].
Press [Cancel Encryption].
Select the data to be carried over to the hard disk and the one not to be deleted.
To carry all of the data over to the hard disk, select [All Data]. To carry over only the machine settings data, select [File System Data Only]. To delete all data, select [Format All Data].
Press [OK].
Press [Exit].
Press [Exit].
Log out.
Turn off the main power switch, and then turn on the main power switch again.
For details about turning off the main power, see "Turning On/Off the Power", Getting Started.
