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
