ESCRIPTION
SECURITY ERASE UNIT (F4h) will transfer 512-bytes of data from the host. Table 20 defines the security
password content of this data. If the
Identifier
bit is set to
Master
, then the password supplied by the user
will be compared with the stored
Master
password. If the
Identifier
bit is set to
User
, then the device shall
compare the supplied password with the stored
User
password. If the password comparison fails then the
device shall report the command aborted to the host.

Notes
:
1. The MACH16 Slim Lite Secure Erase implementation varies from the published ATA
specifications in that the DBT table is not overwritten.
2. The
Erase Mode
bit determines the type of erase selected and the speed at which the command
will complete.

RASE
The Normal Security Erase mode is a quick erase of the media and will result in the loss of all user data
and high-level formatting information. It performs a single-pass of all NAND flash blocks that may contain
user data and is the fastest of all secure erase options.
