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.

It sounds like your drive is bad, based on the behavior of the computer when you remove the drive. Once you remove it, you can boot with some sort of bootable media; but as long as it is installed, you can't.

If you have a similar computer, you could put its hard drive (or SSD) into this computer and try to boot with it. There may be some issues due to differences in the computers or in the setup of each computer; but the other hard drive should basically work in this computer if there is no issue with the computer itself. If the computer basically works with the other drive, then you can be sure that the drive in question is bad.

Thanks for your prompt response. I've sourced a new SSD, and I'm back in business. I'm just surprised by this type of failure, because I've largely read that people are still able to view their drive in disk utility, etc... I was hopeful this type of failure was particularly indicative of repair.

I think it's time I accept the reality...backup more frequently.


Drives don't last forever. Maybe it got zapped by an electrical surge. Maybe it just died. It is probably the circuit board associated with the drive, rather than the drive itself, that is bad. At least that would be my guess if it were a mechanical hard drive, because a mechanical hard drive has a separate circuit board which, if replaced, often brings a dead mechanical hard drive back to life.

I know a guy who keeps a detailed list of every hard drive he installs in his customer's computers. If anyone's hard drive ever goes bad, and another customer has the exact same drive, he will offer to upgrade their drive to a new drive for free, so that he can get their old drive. He will then install the circuit board from that drive to the non-working drive, and this usually revives the non-working drive.

With an SSD, I believe the drive and the circuit board are all one part, and you can't remove the drive from the circuit board. I may be wrong about that; but if you can remove the drive, you could likely replace the circuit board (if you had an exact match) and bring the bad drive back to life.


Be very careful of your source. There are sticks out there from stolen machines that appear to work for the first few times and then lock up. I would buy from someone like OWC or iFixit.
