hey, my friends hard drive just stopped showing up in the computer, no physical damage, nothing. the hard drive works, the light is on, the disk spinning without any strange noises. when i checks the device manager, i saw the hard drive: after that, i went to the disk manager and then i saw that: i tried to use some programs to restore the data, but they run and dont find any files. i think he unplugged the hard drive without the windows safe disconnect. what can i do to restore the data?
