Dead SSD; how to know for sure?
My 2014 MBP froze with a solid cursor, so I forced a reboot. I then was only getting to the load screen, with the progress indicator stuck to 100%. Again, forced a hard reboot. Then, I got nothing, with no picture on the screen, just a dim backlight.
PRAM and SMC reset did nothing, and I wasn't able to boot into any recovery or safe mode, nor use any bootable USB sticks, and I couldn't toggle the caps lock key. I was hearing the chime, but got no apple logo or anything. Not even the flashing folder with question mark. After removing the SSD, I got the question marked folder, I could boot via USB stick, and could even do an internet recovery without any drives attached.
Does a failed SSD present in this way? I figured I could at least boot the computer with a bad SSD, or, does this imply there is a short in the card? Implying it may be able to be repaired, or is it likely toast? I do have a backup, luckily, though, not current.
