Hi there This is a basic 2012 macbook pro 13". I replaced the DVD with the current HDD and installed a new SSD (Kingston V300) out of the box. The new drive is recognised as I get an error after login that the drive is unreadable. Also, the drive shows up in the system report, but not in the Disk Utility, thus I can't format it. I was wondering what the problem could be and how to fix it! Any guesses? I'm doing something with testdisk according to some blogs to rebuild the partiotion table, but i'm not sure if it helps. Please help.
