COMMAND CODE			1 1 1 1 0 0 1 0	REGISTER
	REGISTER SETTING			NORMAL COMPLETION
DR		DRIVE No.		no change
CY				no change
HD				no change

This command requests the host to transfer a sector of data including ones described in the table below .

		Security Unlock Information

Word		Content
0	Control word
	Bit 15-1	Reserved
	Bit 0	Identifier 0=compare user password
		1=compare master password
1-16	Password (32 bytes)
17-255	Reserved

If the Identifier bit is set to master and the drive is in high security level, then the supplied password will be compared with the stored master password. If the drive is in maximum security level, then the SECURITY UNLOCK command will be rejected.

If the Identifier bit is set to user, the drive compares the supplied password with the stored user password.

If the drive fails in comparing passwords, then the drive returns an abort error to the host and decrements the unlock counter. This counter is initially set to five and will be decremented for each mismatched passwords when SECURITY UNLOCK is issued and the drive is locked. When this counter is zero, SECURITY UNLOCK and SECURITY ERASE UNIT commands are aborted until the next power-on reset or hard reset. SECURITY UNLOCK commands issued when the drive is unlocked have no effect on the unlock counter.

10.8.29 SECURITY ERASE PREPARE (F3h)

COMMAND CODE			1 1 1 1 0 0 1 1	REGISTER
	REGISTER SETTING			NORMAL COMPLETION

The SECURITY ERASE PREPARE command must be issued immediately before the SECURITY ERASE UNIT command to enable the drive erase and unlock. This command can prevent accidental erasure of the drive.
