You might try downloading the utility program from the HDD's manufs website and run a diagnostic on the Drive.
Generally speaking when a drive that was visable, is not visable it is because the boot sector has been clobered. You would need to restore the bootsector WITHOUT distroying the File Allocation table (FAT). Possible, but not commonly done.
