RANDOM ERASE Performs 1 to 99 passes (user-selectable),
overwriting with a randomly generated 32-bit
pattern. A new pattern is generated for each
pass.
SECURE ERASE N Initiates the drive’s built-in Secure Erase
(Normal) function. Per the ATA specification,
this function overwrites all addressable areas
using zeroes. HPA or DCO areas are excluded
per the spec, but Drive eRazer Ultra will
unhide such areas prior to initiating Secure
Erase if the user has changed the HPA/DCO
behavior in the Settings menu. Secure Erase
is better able to handle bad blocks compared
to other erase methods.
SECURE ERASE E Initiates the drive’s built-in Secure Erase
(Enhanced) function. This is similar to Secure
Erase Normal, except that HPA and DCO
areas are erased (without being removed),
and instead of all zeroes, a repeating pattern
is used. The pattern is set by the drive
manufacturer.

DSD ISM 6.2.92 Australian government’s data sanitization
standard. Also satisfies New Zealand’s GCSB
NZISM 2010 standard. Removes HPA or DCO
areas, then performs a single pass of a random
pattern (three passes for drives smaller than
15GB).
VERIFY ONLY Does not erase anything. Performs the
verification step only.
3.2.1.2 Custom Erase: If this mode is selected, the
user may select the pass count number, overwrite
type, and overwrite pattern. After an erase mode is
selected, you can make it the default. ENTER saves as
the default. UP or DOWN sets and continues without
saving the selection as the future default.
3.2.2 HPA/DCO Handling
Erase modes Quick Erase, Custom Erase, Secure Erase
N, and Secure Erase E allow the user to select how
hidden areas (HPAs and DCOs) are handled during the
erasing process.
• From the “Review Settings” screen, press ENTER and
then UP or DOWN to get to the HPA/DCO Handling
screen. Press ENTER.
• The current HPA/DCO handling setting will display,
along with an option to change the setting.
Press ENTER to change.
• Use the UP and DOWN buttons to scroll through the
handling options: unlock all, unlock HPA only, and
ignore all. Press ENTER to select.
• After you select the handling, you will be prompted
to make your selection as the default. Pressing ENTER
saves the mode as default. Pressing UP or DOWN sets
and continues without saving as default.
3.2.3 Validation: The user may select the level at
which the Drive eRazer verifies the erasure process at
completion. The options are Minimal (factory default
selection), Medium, and High. This validation process
offers a basic level of assurance that the erasure was
successfully completed. Note: some erase specifications
recommend or require that a separate tool be used for
validation.
• From the “Review Settings” screen, press ENTER,
and then UP or DOWN to get to the “Validation”
screen. Press ENTER.
• The current validation setting will display, along with
an option to change the setting. Press ENTER to
change.
• Use the UP and DOWN buttons to scroll through the
verify options: MINIMAL, MEDIUM, or HIGH.
Press ENTER to select.
• After you select the validation you will be prompted to
make your selection the default. Pressing ENTER
saves the mode as the default. Pressing UP or DOWN
sets and continues without saving as default.
