Is there a way to modify my NVRAM to enable reading and writing SA data in an ATA lock drive (HDS724040...).
I already tried disabling system and non-system heads but to no avail.

If heads are OK, the problem must be with SA modules. You need to upload compatible loader to work with SA.

The hard drive is password locked. As far as I know ARM drives are able to work with SA on partially initialized PCB. And that is what I want, to stop drive from loading SA so I could upload SECI module.

Where are you from ? Are you based in Europe ?

Are you willing to pay for unlocking ?

Maybe your model require for you to load code in RAM to gain access to modules ?

Did you try to unlock it with SeDiv ? What does happen when you do so ? Does it change the NVRam even if it can't replace/patch the security module ?

Ok .... I think that i know what the problem is ...

SeDiv doesn't even read modules on some models of HGST even if they are unlocked ... I think it's the case with the OP model as well ...

As long as the drive doesn't have any special lock like SED/Encryption and as long as it's still ARM IBM BASED (HGST) or whatever and it's NOT something like newer He filled drives i should still be able to unlock those with HRT or even by VSC.
