I have exactly a Same Model HDD with Alwasy BUSY status.
The HDD was received with dead PCB, replaced including NVRAM but it stays alwasy BUSY.

Describe the drive's mechanical behaviour a little. Spin, no spin? Get any heads activity? If so, like what? Spin down afterwards or not? Etc.

Sounds like firmware or heads.
Know the history of the drive? What did the owner say?
Is it from external?

According to customer explanation:
He hooked up the HDD to another computer for data transfer but didn't transfer data, then took back to original PC again and then he sees the HDD isn't working anymore. Later while I found the HDD was with PCB problem, replaced including NVRAM, but no detection. Spinning was normal, but AlWAYS BUSY. That's the history.

Mhh, not a lot that can point to anything specifically. If can't read any of the SA, then likely a heads issue.

As it is always BUSY, so there is no access to SA!
