This was really easy! I removed the hard drive from my mid 2011 MacBook Air and placed it in a free standing caddy - no problem. But it appears that the disk is empty. Is that what it would look like if the hard drive was ruined? (I was told the hard drive was fine - it was my logic board that was fried. So I’m trying to retrieve my data.) Or do I have it inserted wrong? Or… any other explanation?
