Hi everyone I’I’ve being using my mac for almost a year with the Samsung 850 Evo ssd, without a problem. I made a clean install when Yosemite came around and it was workin great. I also updated it to El Capitan and worked smooth. But one morning after hibernation I open it and said there was no disk. Try to reboot, time machine, but nothing worked. Finally I errase everything to make a clean install but after boot my mac wouldn’t find it. I tried to reinstall it inside the mac and using a USB adapter. When using a USB adapter it worked and even boot up. But as soon as I plug it internally and boot it up, the ssd wasn’t found. I’ll appreciate any help. Thanks
Most likely the hard drive IR cable. Apple is now replacing this models cable for free if it fails their test. Try an ASP rather than Apple as they have a financial incentive to help you.
the data ribbon cable connecting the HDD should b replaced
