5 out of 5 eggsYou CAN use TCG OPAL without Motherboard support

Pros: I don't own this HDD. But I have implemented OPAL on SSD without motherboard support. What follows is directions to install & configure a software that takes care of OPAL locking / unlocking and chain loads your actual OS. I use it with windows 8 and it works fantastic.

Cons: Please note that you must power down your machine / HDD for the system to ask you for the password. No password is asked on reboots. The HDD must lose power for it to ask OPAL password again. Not a con, just the way it is.

Other Thoughts: This is just a copy / paste of my notes. Please understand that these are from my SSD install. The outputs that you see from the commands would be different. Replace <password> with your actual password. Please take backup first so you do not lose data because of a mistake, setup errors or bugs etc. Also, it is better to follow the directions from the http://www.r0m30.com/msed website. What follows is a summary of what I did to get setup.

* http://www.r0m30.com/msed
* Test the PBA; worked fine: http://www.r0m30.com/msed/documentation/managing/testpba-1
* Copy the directory locally & install using elevated privilege
c:> cd C:\tmp\msed\msed\x64\Release
c:> msed --scan
\\.\PhysicalDrive0 12 Samsung SSD 850 EVO 250GB EMT01B6Q
\\.\PhysicalDrive1 No HGST HTS541010A9E680 JA0OA590
* gunzip the PBA image if needed; then,
c:> msed --initialsetup <password> \\.\PhysicalDrive0
* Since this is a boot drive
c:> msed --loadPBAimage <password> biospba-<release>.img \\.\PhysicalDrive0
c:> msed --setMBREnable on <password> \\.\PhysicalDrive0
* Enable locking
c:> msed --enableLockingRange 0 <password> \\.\PhysicalDrive0
* Power off the computer to lock the drive. Power the computer on. The PBA should ask for
your password, unlock the drive and chain-load the real OS on the drive you booted from

* If you want to turn off Locking and the PBA:
c:> msed --disableLockingRange 0 <password> \\.\PhysicalDrive0
c:> msed --setMBREnable off <password> \\.\PhysicalDrive0

* Removing the drive from OPAL management
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

1. revert the locking SP.
msed --revertnoerase <Admin1Password> \\.\PhysicalDrive0

2. verify that the locking SP has been deactivated
msed --query \\.\PhysicalDrive0

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

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. msed --reverttper <SIDpassword> \\.\PhysicalDrive0
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.

4 out of 5 eggsSED technology: You need the right mobo

Pros: Am posting this because the Seagate description and the links listed fail to mention something critical. First, SED using hardware full disk encryption is extremely fast and very safe. Hardware FDE creates no performance loss, unlike Bitlocker or Truecrypt software options.

Cons: You need a motherboard BIOS that has an "ATA Password" option separate and in addition to the BIOS password option. The bad news: Most motherboard makers don't have this option, ASUS flatly doesn't offer it. Why? Because it's so secure that if the user forgets their password, no one, NO ONE can recover the data. Lenovo and HP laptops often have this feature, but if you're looking to use it in a desktop, better check your motherboard's BIOS. If ATA Password isn't an option, this disc encryption is non-implementable.

Other Thoughts: ASRock Extreme6 will provide an updated BIOS 1.70B that has ATA Password functionality. You have to email them for it, though.

5 out of 5 eggsI use Seagate exclusively

Pros: The best feature of Seagate Hard Drives is their dependability. I have used Seagate conventional hard drives, as well as their Hybrid Hard Drives. When I replace a hard drive, I always choose Seagate. Why? I've never been let down. My repairs have a very good record, and so I have no reason to use anything else.

Cons: The worst thing about Seagate Drives is: They're not free!
