I was able to recover the data from a workmate’s (home) HD by installing the control board from another HD by the same mfg and built in the same year but had double the capacity.
Wow. That’s cool. I bet that that is what they do when you pay someone to recover a hard drive (or the FBI does it).
Usually the firmware is different and it is tuned to the drive that it is mounted on.
However, the way they double capacity is to simply stack more more platters in the drive. So it makes sense that it would work.
I’ll have to remember that.
That’s an old trick that often works. Transplant the correct logic board onto an alleged crashed beyond repair hard drive. You can buy the logic board on ebay attached to a hard drive...
How often is this all that that data retrieval companies do. 70% of the time???
