Greetings, Looking for some help, I've hit a wall in researching a solution and can't find any scenarios that fit my situation. Backstory: I wanted to upgrade my macbook pro in memory and drive space, so I purchased a compatible SSD to replace my hard drive with. Bought a SATA III 2.5 inch cable to clone my new SSD. On initial hookup the new drive was recognized by disk utility and I was able to reformat it, per the instructions and Youtube videos, and then use a program called SuperDuper to clone it. I thought the clone went by too quick but the program said it was complete. I then unscrewed the laptop and replaced the old hard drive with the new SSD. Once I did rebooted the computer I got the grey question mark file on the screen and I was stuck from there. Reinstalled the old drive and the computer worked fine, but now it won't recognize the SSD so I can try to reattempt the process. My Problem: Why isn't the SSD being recognized in Disk Utility anymore? How do I get it to reappear?
