Problems with Samsung 850 EVO SSD
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
Version Boot ROM: MBP91.00D3.B0B
Version SMC (sistema): 2.2f44
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?
Ist dies eine gute Frage?
