Macbook pro late 2011 and SSD problem

That is most unusual that 4 new cables would not solve the problem. This not going to solve the problem but you can run the Apple Hardware Test twice, with the HDD and the SSD installed internally.

It should not develop an error with the HDD but should error with the SSD. That will confirm that you are dealing with a hardware problem which can be best addressed at an Apple Store genius bar (the evaluation will be FREE).

Your problem is the internal SATA cable will need to be replaced. You prepared the SSD correctly but often the internal SATA cable will work with a HDD but not an SSD. This is quite common so replace it.

Are you saying that one of the images you posted was when you were in the recovery partition? Was that in Internet recovery?

What puzzles m is that in your original post, the SSD worked properly when connected via USB and not when installed in the MBP. If that is the case, why are you trying to erase the SSD? What you have posted suggests that the SSD may have failed. I would retest the SSD externally.

Ciao.

Does the original HDD boot the Mac when installed internally? If not, will it boot the Mac when connected externally via USB?

Test the SSD again to see if it will boot the Mac when connected externally via USB. If it does not, have you done anything to the SSD since the initial formatting and OSX installation?

Ciao.

That all suggests an internal connection problem, usually the SATA cable is not up to standards that will support a SSD. You said in your original post that you changed the cable 4 times with no success. Were these 4 separate cables and were any one of the new?

Ciao.

That surprises me because I know the AHT does test for connectivity to the HDD/SSD. Perhaps my assumption is incorrect. The Apple store genius bar is now your best option and from my perspective your only option for a resolution of this problem. Unfortunately I cannot offer you any more.

I had the same problem with a Samsung 850 Pro. I was told the Samsung 850 pro would not work in my MBP 13 inch late 2011. I finally Gave in a had to get in touch with crucial.com and I bought one of their SSD. Their feed back does say it works well with a late 2011. Funny, my mid 15 inch 2010 MBP works perfect with the same SSD ( Samsung 850 Pro ) that won't work in my late 2011 13 inch MBP. I am waiting for delivery of the crucial ssd. I do think it will work. Another strange things is that I hear the Samsung 850 Pro will work with a Mid 2011 MBP.

Try Recovery mode to erase with Disk Utility and install Mac OS X.

About macOS Recovery - Apple Support

Have you tried to boot into the recovery partition and run Disk Utility from there ans install the OSX?
