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.

Sorry for responding so late. I thought that I will receive an email when someone post in this threat but apparently that is not the case.
So this hard drive is patiently waiting for unlocking.
SeDiv supports this family, it reads and writes modules on my other drives but it doesn't do unlocking. It shows that is writing to NVRAM but NVRAM is not changed at all. I don't think that there is a way to abuse NVRAM in this model like it is in other ones.
Loader is probably the only way to go. I created one and it worked when I tested it on initialized drive, but when it was downloaded to uninitialized one it clicked. So maybe it needs more modules to be included.
I'm pretty sure that it would be easy to do using PC3000...

Please believe me Spildit when I said that SeDiv does not unlock this drives.
I tried modifying NVRAM myself by changing its various parts but all for nothing.
And yes there is no SECI factory module and it is different in every drive but I don't know if its unique to the drive.
