Remove OPAL

The steps outlined below will allow you to turn off the opal locking and return the drive to the manufactured default state **without ** erasing any data managed by the global locking range.

This process has been tested on the following drive/firmware versions:

Manufacturer	Product	Firmware version
Crucial	CT120M500SSD3	MU05
Crucial	CT2000P5PSSD8 (P5 Plus 2 To)	R403
Samsung	850 EVO 500GB	EMT01B6Q
Samsung	960 EVO 250GB	2B7QCXE7
Seagate	ST500LT025-1DH142	0001SDM7

Even though this procedure is part of the OPAL specification there is no guarantee that sedutil is compatible with the OPAL firmware on all drives.

1. revert the locking SP.
   sedutil-cli --revertnoerase {Admin1Password} {drive}

2. verify that the locking SP has been deactivated
   sedutil-cli --query {drive}

look at the query output and make certain that the Locking section shows lockingEnabled=N
--------
Locking function (0x0002)
Locked = N, LockingEnabled = N, LockingSupported = Y,
---------

If the query does not show lockingEnabled=N DO NOT CONTINUE with the next step, if you do all your data will be erased.

3. sedutil-cli --reverttper {SIDpassword} {drive}

When this is finished the drive will be in a non-opal managed state. This would allow you to do anything that you could have done before starting OPAL management under OPAL. You can also reinitiate OPAL management if you wish.
