I have a Western Digital WD1600 Serial ATA hard-drive that stopped working - clicking and no boot. We tried the overnight freezer trick with no luck. It would spin up and then spin right down and stop but the clicking was gone. I happened to have a working version of the same model drive, so I swapped the PCBs.. At that point, the drive spun up successfully, and stayed spinning. I even saw a new entry in my device manager "WDC WD 1600-----" but it would not mount. So I then swapped the 8pin flash chip from the old PCB to the new PCB, and now again it spins up, stays spinning, and the device manager lists the drive "WDC WD1600JS-00MHB0" and says it is working properly. However it still doesn't mount. (I'm on Windows 8 Pro by the way)
Any ideas what a next step might be to try to recover some files from this disc??
