Installing Mac OSX over brand new SSD ADATA SU800

Hello guys. It happens I got a new SSD for my mid-2012 Macbook Pro. Bad news is that when I do Commad+R I'm able to run the disk utility but it doesn't seem to recognize the drive.

I have connected the drive, following this:

https://discussions.apple.com/thread/8259056

and similar other sites with same procedure but no luck.

Drive works flawlessly in my Windows computer (also in another with Linux). I was able to install Mojave on it, via a USB to SATA adaptor hooked to my Macbook Pro. It runs flawlessly, but when I put the ssd inside the computer it doesn't.

Currently, Macbook is running el Capitan over a regular 5400rpm drive (OEM).

Any help?

My intuition is that I'm missing something during the drive initial format. Could you please guide me about how to proceed? thanks!

It is a classic case, HDD runs, SSD wouldn't run.

Owc/MacSales has excellent customer support if you have any questions about compatibility.

Internal SATA cables are actually not cables but flexible circuit boards, usually mylar, with printed circuit traces taking the place of wires. This type of cable can experience cracks in traces due to aging, heat, vibration, impact and abrasion. They can be damaged quite easily if the unit is mishandled during assembly or re-assembly.

In the case of an intermittent generic failure, the electrical continuity of a cracked trace on both sides of the crack is very often a function of the temperature of the unit at the point where the crack exists. As a unit heats up, it expands, and as it expands, the crack widens, eventually forcing a complete electrical separation to exist on both sides of the crack, hence a failure. As it cools down, electrical contact may once again be restored.

SSD= faster I/O speed= more heat in the trace.
