7.3 HDD Wipe
The HDD WIPE option allows you to enable or disable the WIPE operation. When enabled, the
ERASE operation in the Main menu will change to the WIPE operation (see section 6.2 Erase / Wipe
on page 22). The Wipe operation ensures that the hard drive is completely erased and that the data
is unrecoverable.
Unlike an Erase, which writes zeros to every sector on the hard drive, a Wipe is a four step process
that ensures that data is unrecoverable. The four steps are as follows:
1. All sectors on the hard drive(s) are written to with 0’s.
2. All sectors on the hard drive(s) are written to with 1’s.
3. All sectors on the hard drive(s) are written to with a random pattern of 0’s and 1’s.
4. All sectors on the hard drive(s) are verified
Tap the ‘RUN’ button to change this option’s setting.
• [ ] – Wipe disabled (default). The wipe operation is turned off and in the Main menu you will
only see the ERASE option.
• [ ٭ ] – Wipe enabled. The wipe operation is turned off and you will now see the WIPE option
in the Main menu instead of ERASE.
When you enable the WIPE operation, the system will ask you to configure the number of Wipe
Cycles. The Wipe operation can be run consecutively up to 999 times. 7 wipe cycles complies with
the American DOD 5220-22.M standard.
Note: The more Wipe Cycles you set, the longer the wipe process will take.
To set the number of Wipe Cycles:
1. The digit furthest to the right will be blinking, indicating that it is currently selected. Tap
the ‘RUN’ button to increase the value by one.
2. Tap the ‘SET’ button to select the next digit to the left. Tap the ‘RUN’ button to increase
the digit by one. Repeat this step as necessary.
3. Hold the ‘RUN’ button to confirm.
