Overwrite All Data Function

2.16 Overwrite All Data Function
When a log-on to the Administrator Mode becomes successful, the machine enables setting of the operation
of the Overwrite All Data function.
When the machine is to be discarded, or use of a leased machine is terminated at the end of the leasing con-
tract, the Overwrite All Data function overwrites and erases all data stored in all spaces of the HDD. The func-
tion also resets all passwords saved in the flash memory and eMMC to factory settings, preventing data from
leaking. For details of items that are cleared by the Overwrite All Data function, see page 1-16.
The HDD Overwrite Method offers the choice of eight different modes, [Mode 1] through [Mode 8]. Overwrite
All Data takes about less than one hour in [Mode 1] at the minimum and about 9 hours in [Mode 8] at the
maximum.
