Help unlocking/erasing or flashing HP SMKR4000S5xeN7.2 to generic Seagate firmware

[tiboo86]

Good morning,

I recovered several discs from an HPe 3PAR 4TB bay. The disks are well seen in my raid card, however it is impossible to create a VD. The disk automatically goes into Failed / Offline.
In Niagara, I see the disk as Unknown. It seems to be a Seagate ST4000NM0034 drive but I can't find the firmware on the internet.
Do you have any idea so that I can use this disc.

THANKS

Here is fw for your drive http://files.hddguru.com/download/Firmware updates/Seagate/EntCap-Makara-STD-SAS-5xxE-E0G5.zip but more likely you can't download fw to HP branded drive
