Disable SED functionality on Samsung 840 EVO

Hi experts.

Using Samsung's Magician software, I enabled the self encrypting capabilities of that drive ("Encrypted Drive").
Now I have reasons to undo that, but magician says
Once Encrypted Drive is enabled, it cannot be disabled directly or reverted to ‘Ready to enable status' by the user using Magician. Please contact the supplier of the subject operation system (Microsoft) or customer support for details.
Since I don't like Samsung's support so far and since I am sure Microsoft will not know, I came here, first :)

How to disable it?

One method:

Call 800-Samsung, menu can produce errors if you don't wait for menu spiel to finish and get to the point where
it says, "Press 1 for" or "Press 4 for" so go slow and let it get through.
push 1 for consumer (because product is consumer product)
1 for first time
4 for computer
5 for drive
1 for SSD

You should have arrived at support group for SSDs and have one of four guys knowledgeable about this.

Get RMA number
ship drive to them
They use revert tool and it wipes drive
get drive returned.

Another option according to the Samsung rep:

Look into Lenovo forum by internet search where someone posted the Lenovo Samsung PSI revert tool.  Search Lenovo Samsung PSI revert tool.  It is a year or two old so is not the current version but may do the job for you.  It will depend on the machine and the permissions setup.  Then you can possibly wipe your own disk.  The ZIP download includes instructions.  The rep said he personally had done this once and the Lenovo OEM version of the Samsung tool worked for him.

I was not able to locate the Lenovo forum post but found the following link for a Samsung PSID revert tool:
