Table 131 Security Erase Unit Command (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. Host MAX LBA set by
Initialize Drive Parameter, Device Configuration Overlay, or Set MAX Address command is ignored. So the
protected area by Set MAX Address command is also initialized.
This command requests to transfer a single sector data from the host including information specified in Table
131 on the page 182.
When security is disabled and the Identifier bit is set to User, then the device shall return command aborted.
