Hitachi pcb changed

[jtb1982]

I receive a hitachi hdd the model is HTS545050A7E362 and the pcb is changed, with the pc3k i read the rom serial number and is not the same serial number as the label, I don't have much experience with this brand, the client already went to 2 mac technical services and in the last place they changed the disk from the laptop, I even believe the technical service give my client a brick. And I don't believe the client can recover the original pcb.

I want to know if it is possible to rebuild the rom from the firmware like in WD? or do some sort of hot swap? I I know the last method is not very possible. When I search in the blog all similar questions the answer is no, I only ask if there exist some exception.

Thanks to all to read my post
My best regards

Hello ,
Please Share The ROM and Top Label of The HDD

SN is byte swapped, take it into account.
If it still doesn't match, you either have to have the client to get orig pcb or i can help with recovering the nvram and the data from the drive.
