I had a WD external My BOOK 1 TB now the SATA USB controller on that had gone bad so I opened it and installed the drive directly to my Computer.

Problem is I had a large 930 GB partion of FAT 32 on that which was accessible through USB interface but when I am connecting it to SATA the drive shows in Device Manager but not in my Computer.

In disk management it shows as Unallocated space, I know formatting it will show the drive but I want to save the precious data on drive.

So How?
Any solution.
Quick thought, If I connect it through a casing that are available in market of Sata to USb will it work? As it will be same interface again
