If Secure start-up is turned on and an incorrect password is entered
more than a specified number of times, the device will automatically
initialise.
If you forget your decryption password, you must initialise the device to
use it again. Initialisation will delete all data saved before initialisation.
Encryption takes place when the device boots for the first time after a
factory reset. Stopping encryption before it is complete may damage
data.
