    You're sure it's an SSD? Not a regular hard drive? A hard knock would cause a regular hard disk to scratch the platters on the drive, causing data loss. I find it hard to believe that a bump would cause an SSD to malfunction in that way.

    Perhaps if it is an SSD the SSD was knocked loose from its connector?

    Enter BIOS setup to see if SSD is detected. If not reseat it in drive port to try to get it detected. If not then contact manufacturer's Tech Support to run drive diagnostics for possible RMA if under warranty.

    I'm sure it's an SSD
    Agree knock may have nothing to do with my problem
    Have reseated with no resolution of my problem

    Google the verbatim error and codes to see how others resolved it.

    Keep working through steps. I'd test and Disk Check HD.
