macrumors newbie
I have a mid 2012 13 inch Macbook Pro and installed a Smasung EVO 850 SSD 250 GB disk replacing the HDD. I was able to format it correctly and install the MacOs through the internet recovery with no problems. Everything was working perfectly when a few weeks ago after a seamingly normal hard reset, because of system stalling for no apparent reason, it did not boot up again.
I went into recovery mode and could not repair or format the disk, not even doing a repartition of HFS+, it gets stuck on 50% saying 'Waiting for disk to reappear.' (I'm ok with doing so since I didn't have much data to lose). According to some foruns I tried partitioning in Fat32 (with success) and reformat back to HFS with no luck. Then, I tried booting up from an Ubuntu distro running on USB pen, and managed to format it, write to it, read from it, mount it, repair ir, and every other action gparted is able to do, I even managed to format it in HFS+ (download appropriate linux packages) and it went well, but not with disk utility, nor could I manage to install a new OS on top of the Ubuntu HFS+ formatted disk.
After reading more foruns I found that it could be a Sata cable problem.
My first question is, since it works perfectly well on Ubuntu, the SSD, how could the cable or the disk be damaged?
On researching this Sata problem, I found that it could be easily fixed by putting some tape to isolate the cable from the bottom of the alluminium pc cover. I did so and apparently after it, I could format the SSD to HFS+ using disk utility and install the MacOS. However, it failled. I already tryed 3 times and never succeeded.
Did anyone experience similar issues? What do you think is the problem SSD? Sata cable?

Best performance upgrades for MacBook Pro 2012 500gb. MacBook Pro 13-inch, Mid 2012. 2.5 GHz Intel Core i5. 16 GB 1600 MHz DDR3. By [email protected]. Upgrading your internal hard drive to an SSD (preferably a Samsung PRO series) will increase performance noticeably, and may squeeze out a little extra battery life as.
Conclusion
First of all it's Samsung 850 Evo 500 GB drive that I have - not the 840. After I installed Lion on my old HD successfully I managed to access Samsung SSD via SATA to USB cable and formatted it via disk utility tool in Lion. Than I made bootable USB of El Capitan using terminal and managed to install fresh El Capitan on HD but when I tried to do so on SSD I failed couple of times. When connected internally SSD sometimes would be shown, sometimes not and at one of the tries installation crashed during the process. I just couldn't install macOS on SSD even I was making the right steps all along. So I continued my research and found that the HD SATA cable (or data cable) might be the cause. I did couple of more tests - plug in, plug out, trying variety of things and based on that concluded that this could easily be true. So before I purchased a new one I tried the isolation tape fix which is well explained here:
and it worked. I'm writting this from El Capitan using the very same SSD.
I hope that this example will help someone else and the overal development.
