HDD no being recognized
 

I recently swapped a HDD over to my new copmuter, does not have OS just data drive. At first it didn't spin or power up, determined it was a PCB fault as i saw the blown circuit. I swapped out for a new PCB of the proper one and not the HDD spins and powers up but the bios and OS do not recognize it. I've tried different computer, ports, cable, enclosures with no luck. This was my data backup drive and its got alot of important information on it. Any help would be great.

Does the drive come up in Disk Management at all?

negative, just sounds of it spooling up, not recognized in bios, OS or disk managment

PCBs that look the same are not always compatible. I discovered this by trial and error.

u need to find a PCB that has the same identical revision then it "should" work

swapping PCB should be the last thing to do when a HDD is dead. It is as difficult as brain surgery.

yah. matched brand, model, series and firmware. just spools like its perfectly normal but doesn't get picked up.

Silly question but is the port enabled/active in the bios?

yes they are, ive tried all ports, different comp, external case, on my NAS cabinet.. nadda
