Problems with Samsung 850 EVO SSD
Hi
A few months ago I replaced the old HD with a new Samsung 850 EVO SSD 500 GB
But yesterday my system wouldn't start! I tried AHT and the result was 4hdd/11/400000004 sata (0,0)
So I put the old HD back in and the MacBook was OK, and it started. I tried to see if the SSD was broken. But I can use it with no problem externally.
Is it possible that the SATA cable is broken or too old for the SSD?
Thank You, Sorry for my english

I tried to upload but it says that I need 10.8.5 or 10.9.5 but i've 10.10.4.
Is it possible to test the SATA cable?
