    M.2 SSD no longer being recognized


    Six months or so ago I purchased an M.2 SSD and transferred windows from my old SSD to the new one. I've had no issues up until today but when I tried to boot my computer, windows randomly didn't recognize my SSD. It said reboot and select proper boot device. I've tried taking it out and putting it back in again, I've swapped from UEFI to Legacy as I've read is a possible solution online but neither worked. I can't access windows so my options are pretty limited right now.

    Do you have a second m2 port to try?

    Do you have any particular reason to think the drive is not dead and gone?

    I don't have a second m2 port unfortunately and no other way to test it. The drive isn't old but I suppose it could have been defective. The only thing I can think of is last night when I shut it off I accidentally click restart instead of shutting it down and rather than wait for it to restart, I held down the power button. That seems like a stupid way to kill am ssd but that's all I can think of.

    Is the M.2 disk recognized on BIOS?
    If it isn't, it's probably a hardware problem and you should as for a new in warranty.

    If it's recognized on BIOS it's probably a corrupted software.
    Boot from a Win 10 installation disk, launch a cmd window (Shift+F10) and type:
    diskpart
    list volume (take note of the letter assigned to your windows in the M.2 drive)
    exit
    sfc /scannow /offwindir=X:\windows /offbootdir=X:\ (replace X with the drive letter found with list volume)

    My recommendation is to create a utilities disk Windows 10 Recovery Tools - Bootable Rescue Disk

    Quick question before I do the previous steps. Would I have issues putting an SSD with windows from an old computer into my current computer?

    Yep. It would disable the m.2 since some motherboards have the SATA bus tied to the m.2 port.

    What if I plug in the old SSD using a USB adapter? Same results?

    Nope. Only if on SATA.

    So I did go ahead and plug in my older windows SSD and I do see my new M2 drive (now the D drive) and all of the files on it. I have tried using a recovery CD to scan for errors and restore the startup of it but haven't had luck yet. So obviously the drive itself still works but still unable to boot from it for whatever reason.

    If you have a Macrium Free boot USB, you could try booting from that and if it then see's the m2 drive, choose Macrium's fix boot. Best done if the m2 is the only drive connected to avoid conflict issues.
