Crucial SSD 512gb not detected internally
My MBP 13" Unibody Late 2011 is not detecting Crucial SSD 512gb even after I replaced the sata cable purchased from ifixit.com
I currently have Sandisk SSD 256gb and is working good. But I have also bought Crucial SSD 512 to upgrade my existing SSD to double capacity.
I realize that this new crucial (512gb)SSD works if I connect as external USB drive and load OS also. But when I place inside replacing my current SSD, it does not work. There comes a '?' Folder Icon and can't proceed.
Looking forward your suggestion to resolve my current SSD upgrading issue please!
