Is the disk visible from "lsblk -f" under Linux? Detecting its existence is different than detecting partitions. If it shows up, but fails to allow mount, then there is more hope than if it just doesn't show up at all. If it doesn't show up at all, then try a different SATA port. If it fails to show up on any port, then you are somewhat screwed. If this is an old style mechanical platter hard drive, and if it shows up but fails to mount, then there are ways to maybe get some of the data back. On the other hand, the other user is right: It has to come from a backup or from a data recovery service (if electronics are bad such that the disk does not have an electrical interface a data recovery service will disassemble the drive and put replacement electrical parts in it to make it available; if it is the disk platter and not the electronics, then there are tools to pull available data and accepting lost blocks which normal mount would fail under).
It’s not something I have really looked into but I remember reading you cannot swap pcb’s on HDD’s as the controller has to be synchronised/adjusted to the drive. Any slight discrepancy and the heads will not align and can cause damage.


You can't just slap on a replacement PCB and expect things to work. It's a more involved process.

And, in any case, more often than not, it's not an issue with the PCB.

This is most likely now a job for a professional. It can be fairly expensive, but just like not replacing the filter in your furnace or the oil in your car, skipping preventative maintenance -- in this case, regular backups and ideally multiple backups -- can be very expensive.

I recently had a hard drive die on me. My heart sank upon seeing the message that it had failed. As a web developer, I knew immediately that there was no hope of retrieving my work. I tried everything possible to resurrect this project and salvage what I could, slowly losing hope as each day passed. Finally, after a week of trying to recover data from the dead hard drive, I gave in and purchased a new one. This article will teach you how to recover data from a dying hard drive and how you should do it (and why).
You should never be in a position to have to try to 'recover' data from a dead or dying drive.

This is what proactive backups are for.
If any of my drives were to die right now....completely dead...I'd just recover the data from the very recent backup.
