4.4 hDD Wipe
The HDD WIPE option allows you to enable or disable HDD Wipe operation. When enabled, the
ERASE operation in the Main menu will change to WIPE (see section 3.2 Erase / Wipe on page 18).
The HDD Wipe operation ensures that data on the hard drive is completely erased and unrecoverable.
Unlike an Erase, which writes zeros to every sector on the hard drive, a Wipe Cycle 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

Note:
Data on SSDs may not be permanently deleted by the Wipe function. Due to the differences
in technology between magnetic platters and flash based memory, sanitation techniques which are
known to permanently remove sensitive information from HDDs may not be as successful in removing
data from SSDs.
