Initially my MacBook Pro Late 2011 failed to boot, it shows a folder with question mark on it. In internet recovery, the hard drive is not even showing up in Disk Utility.
So I thought the hard drive failed. Bought a SSD to replace the hard drive. Then I tried to install El Capitan on the empty SS . . .
Thought it was a hard drive failure, bought a new hd only to find out it was either the cable or mb. So went the cheapest route first.
make sure you get the cable with the little bracket that holds the hd in. Its a little more expensive but well worth it.. after I replaced mine I disconnected the . . .
Macbook crashed, did an online search, found ifixit youtube video of how to replace hard drive and cable. Removed hard drive and tested using a sata to usb cable. Hard drive functioned, process of elimination left the cable as the failure.

The HD in my 2011 MacBook Pro started to fail. I decided to replace it with a 1T SDD.

All signs of a bad hard drive, but pulling the drive and connecting to another Mac showed the drive was working just fine. After some research . . .
My main HD crashed. I decide to buy a SSD. After installing it, the system will identify it but, won't let me erase it.

After some research I found out there documented issue related to the damaged cable.
The low cost of the part made it easy to give it a . . .
My daughter was told her MacBook Pro HD crashed, and was sold a new HD. She was then told her mother board was fried, and was sold a new MacBook.
