Got this hdd, one day just wouldnt start up. Makes absolutely no knocking, clicking, or other noise. my docks won't recognize it but my other hdds show just fine.
Purchased a new board and swapped bios chips thinking maybe one of the fuses blew or sometghing but the same issue persists. Drive is fully encrypted idk if that complicates things.
There are some good videos by Alex on troubleshooting and fixing Hard Drive boards that are not powering on. If you can figure out where the problem is Main Board or inside the disk then you can figure out you next plan of action. Go through the videos and see if you can rule out the main board as your problem.
