I'd attached my missing drive to an another linux os named xubuntu, trying mounted my drive using Gparted, then I found the Error "The primary GPT table is corrupt, but the backup appears OK, so that will be used." After then i follow this thread https://ubuntuforums.org/showthread.php?t=2377227
Now its working fine.
