The patient is Hitachi HDT721010SLA360 which spins but is not recognized on PC3000. After swapping NV-RAM to a fine pcb the behaviour remains same. Any hints how to check the validity of the patient's NV-RAM and how to read its' content?

why swapping NV to new pcb?
how did you know its PCB issue?
and does it click when you power it on?

I could not read the content of the NV-RAM of the patient. So I had no other choice (to my knowledge).
It does not exactly click it's just trying to read and then stops spinning.

Power it up in ur 3k
and select the family and see if it reads it
those Hitachi hdd`s are tricky

That's what I've been doing since the NV-RAM swap. PC3K is not recognising the drive. The drive is a kind of trying to read initiative data but after couple of seconds it stops spinning. No clicking no other wierd sounds either. I'm out of ideas.

I've got almost the same problem so if you have a solution. PM me!

Almost? Can you clarify?
And what tools do you have exactly?

Place donor PCB with non-native ROM. Maybe you get SA access. If not, then adjust SA top values (or use NV-RAM Adjustment feature) till you can reach SA. Then read NVRC module.
If NVRC is bad, search in RAM for native NVRC copy.
