I/O errors after logic board swap
August 31st, 2020, 21:03
I have a seagate drive that was killed by a bad psu when moving my computer to a new case the psu made a pop sound and went poof.
The drive is one of 2 that no longer spins up or makes any sounds. The original board has a short to ground near the connector where the sata/power delivery traces are, there should not be any damage physically as the drive worked perfectly fine before the PSU killed it.
After swapping the logic board and moving the bios chip to the new board the drive spins and makes noises but i get i/o errors and the drive shows up as 3.86 gb instead of 3.86 TB. Should i try a new logic board in hopes that i just got a bad replacement board? I need help with figuring out next steps to repair this drive as this is my first attempt at something like this and maybe i missed something? Is my BIOS chip fried?
I'm just at a loss as to what i can do next besides paying for a platter transfer at a data recovery place, which i would rather avoid as i have seen the horror stories online.

Its this drive/logic board https://www.hdd-parts.com/15103520.html, forgot to put this in the initial post

If the 5V TVS diode was shorted, then it is possible that the overvoltage took out the preamp on the headstack.

so im assuming next step would be sending to a shop to have the heads/platters swapped or transferred? Is this possible to do myself without a ton of specialized tools?
Im aware i would need laminar flow or a clean environment as well as a donor drive and headcomb

I'm not a DR pro, but I would think that a DIY headswap, assuming that is indeed the problem, would be unlikely to succeed.

Mathematical chance of succeeding is above zero, but it is less than 10% based on my experience (lot of tampered drives coming in where users thought it could be done at home).
I think i will receive critics for being too optimistic
