Ever since my macbook pro went flat my hard drive no longer is recognised on the computer. it comes up with the first picture uploaded. when I go to disk utility I can not click verify disk or repair disk but can see the hard drive there. I have no idea how to fix this without losing everything on the hard drive. I have no other mac to plug into and I plugged it into a pc but it does not show up, however the sounds when you plug something in and out are there.
