A year ago, I modify my 2011 bacbook pro 13 with a SSD OCZ agility 120Gb It works great... for a year. It just stop working and during recovery Disk Utility don't see it. I asume that was the disk and I get a new one. A Kingston HYPERX 120Gb. After installation, running Disk Utility again, SSD was detected, but it need format in order to install OSX. After format, I get error during the start of the installation process. Rebbot the machine and Disk Utility doesn't regognize any more the SSD. Any ideas? Tks for your help!
