12.32 Security Erase Unit (F4h)
Table 127: Security Erase Unit (F4h)
The Security Erase Unit command initializes all user data sectors and then disables the device lock function.
Note that the Security Erase Unit command initializes from LBA 0 to Native MAX LBA. The Host MAX LBA is
set by the Initialize Drive Parameter or the Set MAX ADDRESS command is ignored. The protected area by the
Set MAX ADDRESS command is also initialized.
This command requests the transfer of a single sector of data from the host including information specified in the
table below.
If the password does not match, the device rejects the command with an Aborted error.
Table 128: Erase Unit information
Identifier
Zero indicates that the device should check the supplied password against the user pass-
word stored internally. One indicates that the device should check the given password
against the master password stored internally.
The Security Erase Unit command erases all user data and disables the security mode feature (device lock func-
tion). After the completion of this command, all the user data will be initialized to zero with a write operation. At
this time, the data write is not verified with a read operation to determine if the data sector is initialized correctly.
