HDD troubleshooting could I make working disks from these?

Hi,

 

first time poster because I don't know any better place to post this. 

I could buy these three dead(ish) 8TB drives for 30€ (~$36).

 

They all have different error/symptoms:

- One of them doesn't recognize at all.

- Second one says servo/seek error.

- Third recognizes as 1.4TB drive.

 

Do you think these could be salvaged or combined to make at least one or two of them to work. Maybe swap pcb from servo error disk to the one that doesn't show up at all? Or maybe the servo error disk has just jammed heads.

Obviously these would not be very reliable drives by any means but I'm taking this just more as a challenge and project that might reward me with one working drive.

 

You think there's any hope to make one of them work?

You would need to swap the BIOS (or equivalent) chip on the boards to do that.

The PCB is software locked to specific disks/readheads? That sucks. 

Well maybe I could desolder the chip if I figure out which one it is.

Judging by the build of the drives, they're probably helium drives, so the moment you open them, they're shot.

Can't see well from this poor image, but these look like Helium filled drives like someone poited out already. These are unserviceable. Besides, even swapping controller boards between drives doens't work in most cases because the drives are calibrated during manufacturing and baked into the controller.

 

First is totally dead, second one probably has dead head motor and last one probably has dead read/write heads on certain platters. Don't bother imo.
