Seagate constellation ES 2TB

[jugs]

Hi

I got a Seagate constellation ES 2TB with board issue , i replaced the pcb with rom swap. now is the hdd is detected but it shows no partition . when tried scanning in R-studio no files were found.
When i see the 0 sector it shows as pic attached.

when the drive is connected to the terminal it shows message encrypting in terminal.

is it some sort of encryption ? i asked the customer whether he used any encryption he says no.

looking for suggestion
