Remove OPAL (--revertnoerase) Fails

[mabachel]

Hey,

I did not specifically tested your RESCUE64.img to Remove OPAL since I suspect it is not compatible due to SHA512 use instead of SHA1 but because your source is based on DTA's version 1.15.1 which I use, I guess your version is also affected.

Check out the issue here: Drive-Trust-Alliance#304 (comment)
and here: ladar/sedutil#11 (comment)

Thanks for the heads up.

Remove OPAL on this repo is working on the EVO 850 in a T470 Thinkpad. We'll keep an eye on this Issue.

May I have to set some flags differently first? Can you compare a query of your 850 EVO with my query to check it, please?

It seems you first need to disable locking, and set mbrenable to off:

sedutil-cli --disablelockingrange 0 PASSWORD /dev/nvme0
sedutil-cli --setmbrenable off PASSWORD /dev/nvme0
sedutil-cli --revertnoerase PASSWORD /dev/nvme0
sedutil-cli --reverttper PASSWORD /dev/nvme0

Beware with the reverttper command.

@mabachel we don't have the 850 T470 setup anymore.

Did you get the issue resolved?

sedutil-cli --setmbrenable off PASSWORD /dev/nvme0

Thanks! It worked like a charm for me. The Documentation / Wiki should mention this.

This issue can be closed.

I think the latest command issue is better described here: https://github.com/Drive-Trust-Alliance/sedutil/wiki/Remove-OPAL
