Supported Erase Specifications
The Drive eRazer Ultra offers user flexibility with over a dozen preset erase methods. Use the fol
-
lowing chart to help select which erase specification to use.
MODE
DESCRIPTION
QUICK ERASE
Performs a single pass, writing all zeroes
CUSTOM ERASE
Performs 1 to 99 passes (user-selectable) overwriting with zeroes for a user-
selected pattern. On every other pass, the complement (inverse) of the se
-
lected pattern will be used, but the last pass will always use the user-defined
pattern.
RANDOM ERASE
Performs 1 to 9 passes (user-selectable), overwriting with a randomly gener
-
ated 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 speci
-
fication, this function overwrites all addessable areas using zeroes. HPA or
DCO areas are excluded per the spec, but the Drive eRazer Ultra will unhide
such areas prior to initiating the Secure Erase if the user has changed the
HPA/DCO behavior in the “Review 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 pat
-
tern is set by the drive manufacturer. The validation step is not applicable since
the erase pattern varies from drive to drive.
