Help Failed HDD

Well i received the PCB board today and took it along to a repair centre who fitted it onto the drive with the bios chip.

But no luck, the changes had no effect on the drive at all.

Looks like I'm going to have to seek professional recovery help, if that's still even possible.
 
Sorry to hear that
Was hoping pcb change would
Work for you
Never had to resort to professional data recovery
Do any of them do no data recovered no fee?
Would be even worse if its unrecoverable
But they still give you a hefty bill
 
As I said previously, John at Lazarus Data Recovery.

Gave them a call and they have an additional upfront £50 fee if the drive has had any work already.

There's a local company I might try, they have some good feedback too.

Well put it another way, the more you mess around with sending it to random people/companies to "have a go" the more likely you are to lose the data.
 
Just to give an update on this.

The reason I avoided going with Lazarus was purely because I wasn't sure I could explain the problem without being face to face and pointing out the changes made to the boards.

Anyway the local repair company I approached have managed to save the drive and the data :D

Basically as suspected the original board blew some diodes when I'd connected the incorrect power supply.

But it also turned out that the replacement board I'd got was also shot.

So these repair guys worked on the original board and were able to repair it and reactivate the HDD.

Well that's one lesson learned the hard way, ALWAYS BACK UP YOUR DATA!
 
ALWAYS BACK UP YOUR DATA!
So say all of us!
I even use vmware converter to turn my desktop into a vm (periodically) so I can take my time if the worst happens.
 
Long time so maybe 25yrs ago I had a drive with a pcb failure. I'd bought two identical drives at the same time and was able to swap the pcb and recover the data.
 
These days I just keep multiple copies of my data on different drives.

I also keep old versions of my data not just copies of the current data. Because I've deleted some thing by accident or had it corrupted. But not noticed until I've copied it into all my backups.
 
For all those who are struggling with the data recovery, here is a good tutorial to restore data from a crashed hard disk https://www.cleverfiles.com/howto/crashed-hard-drive-recovery.html. Also suitable for an average computer user, not only tech-savvy guys. At the beginning might sound a little complicated or tricky, but it gets much easier when you actually start doing it.

How valuable is the data, if it has any value at all then look at using a professional company, its very easy to make things worse when you dont know what you are doing.
Using the company would be the next step probably, for now i am going to try to restore files from failed hard drive by myself, following this guide https://7datarecovery.com/blog/recover-failed-hard-drive/. In case this will not work, of course i will try to find someone who can do it for me.
Hopefully it will not come to that and i will be able to solve the issue myself.
