A couple days ago my MacBook, an early 2016, 12-inch, Retina model had a hard freeze, rainbow wheel and screen frozen.

After a forced restart holding down the power button I was able to get to the login screen but my password would not work.

After additional restarts I was greeted with the Flashing ? Folder icon for no startup disk.

I tried it number of times, making sure I was not doing caps lock or anything of that nature. I was eventually able to get it running by installing macOS Mojave to an external drive however...

The internal hard drive does now show up in anything: Disk Utility, diskutil list,System Information App > Storage, Recovery Mode / Only Recovery Mode etc.

The HDD on these models is soldered to the board so I cannot remove it for further testing.

Does this mean that my SSD is totally done for? Are there any other ways I can access it and test it?

Below is my output from diskutil and some screen shots from Recovery Mode

EDIT: The 319GB Drive is my external WD Hard Drive I am booted from, the CD sized drive is one of those built in partition on an external drive where the recovery software they bundle is stored.

The Internal Drive is not showing up at all and should be 512 MB.

Find below the system_profiler terminal output:

  • Something's definately up with your drive because 319GB is an awfully odd size; the 2016 12" MB came with 256 or 512GB. Is Bootcamp installed by chance? Also try this (I've never done this in recovery so let's see if it works)... Issue the command system_profiler SPStorageDataType and post your results. Let's see what the system sees with respect to storage devices.

  • I've seen (spinning) drives go bad and report strange capacity numbers that have no basis in reality. I would guess that the SSD in this Mac died, but if someone else comes up with more things to try, it's probably worth it. Start with @allan 's suggestion Commented Mar 21, 2020 at 0:12
  • @Allan - Sorry that was unclear of me, the 319 is my 350GB WD External I am booted from. The internal drive is 512GB. I will edit the post for this.

  • @Steven Chambers - Sorry to be unclear, the 319 Is my WD External, Not a strange size for the internal drive, the Internal is not showing up at all.

Yesterday I had the same problem and solved it by creating a bootable USB with Mac OS Mojave.

Next you need to power on the Mac while holding Option, then select "boot from USB". Wait and open Disk Utility and the SSD will be there.

This solution worked for me. I think disk utility in network recovery is limited or is a old version without support.
