It looks like the M.2 drive is 128GB rather than 256 GB unless there is a hidden partition. Only 3% free space is not good, you want to leave a minimum 10% of SSD's free.
Hopefully the D drive (Spinner) has a slightly loose connection. If you have any critical files on it, back them up somewhere just to be safe. Don't worry about games and other programs where you have the original installation disks or can download again.
If you are comfortable opening up the back of the laptop to look for a loose connection then you can do that. Otherwise, just keep using it and if it happens again, take it in for repair (I assume it is still under warranty). I don't know if opening it up will void the warranty, someone else here might know...
