8.2.27 Security Unlock (F2h)
This command transfers 512 bytes of data from the host. If the Identifier bit is set to Master and the device is in high security level, then the password supplied shall be compared with the stored Master password. If the device is in maximum security level then the unlock shall be rejected.
If the Identifier bit is set to the user then the device needs to compare the supplied password with the stored User password.
If the password compare fails then the device shall return command aborted to the host and decrements the unlock counter. This counter shall be initially set to five and shall be decremented for each password mismatch when SECURITY UNLOCK is issued and the device is locked. When this counter reaches zero then SECURITY UNLOCK and SECURITY ERASE UNIT commands shall be command aborted until a power-on reset or a hardware reset. SECURITY UNLOCK commands issued when the device is unlocked have no effect on the unlock counter.
8.2.28 Seek (7xh)
This command has become obsolete in the ATA7 specification. The supporting of this command is just for backward compatibility purpose.
8.2.29 Set Features (EFh)
This command is used by the host to establish the following parameters, which affect the execution of certain drive features as shown below.
