SSD showing in Bios and Device Manager, but nowhere else


Yesterday when navigating in my E: drive SSD ( Samsung 850 EVO ) folders, the window crashed and the explorer.exe (or whatever it's called in Win10) followed, forcing me to force reboot my computer by pushing the power button.
It then prevented me from accessing Windows for a few reboot, asking to analyze something (which I let it do so after a few try) which turned out to be my C: drive (my second SSD where Windows is installed). It analyzed and "repaired" it, and a few forced reboots later I was finally able to get back on Windows.

With one little problem...

My first SSD ( the Samsung 850 EVO E: ) completely disappeared from my computer and Disk Management. I looked at the BIOS which detects it fine, and after looking for a bit I noticed it also appears on my device manager, which tells me that the disk is fine, with up-to-date drivers and so on.
Yet, I cannot find a way to make it appear on Disk Management or directly back on y computer.

Some friends of mine told me it's probably dead, but the thing isn't even 6 months old, wasn't used THAT much and I never used more than approx. 1/5 of it's total space. Also, the fact that i'd appear in my BIOS and my device manager seems weird to me if it'd really be dead.

I already tried to plug it in another port, without any change.

My BIOS was, and is still in AHCI.

Any thoughts on that ?

Thanks in advance for any answer.

  1. So when you used the Samsung Magician program to test the health of the SSD, what were the results?
  2. From Windows, if you run DISKPART from an elevated command prompt and then run List Disk do you see the SSD listed?
    Is there data on there that you need?
    If not, you can delete the partirions and reformat the SSD from the command prompt, directions are here:
  3. Hello, and thanks for your answers.

    @ArtPog The Samsung Magician program doesn't detect the SSD. I can only see it in the BIOS and in the device manager

    @BadAsAl The SSD doesn't appear in DISKPART, even if I run it as admin. I do not specially need the Data, it's just games that I'd need to download again. But since it's not on Diskpart, i don't think I can use your tutorial to partition it (or at least I fail to see how)
  4. You mentioned plugging into a different port, I am assuming SATA. Did you try a different SATA cable and also power cable?
  5. I plugged it in another SATA port indeed. As for the cables, I just tried using a spare SATA cable with no difference. As for the power cable, it's plugged on the same one a my 2 other drives. I tried switching the "port" (don't know how it's really called, but the areas where you can plug things on your cable) of the power cable with one used on another functional drive, with no result too. The functional one stills works, the other one still doesn't.
  6. Assuming you have a USB external enclosure that can accommodate a 2.5" drive (or one of those USB-to-SATA cable adapters), try connecting the drive that way and see if it can be accessed. If so, run the diagnostic program.

    Or, if you have access to another PC try connecting the drive in that machine as a secondary drive.
  7. Hello,

    Sorry for the long answering time, but I didn't have an USB external enclosure and I had to find a friend that a computer in which we could try the drive.
    Anyway, we did it, and it's not working any better on the other computer than on mine.
  8. Just to confirm your latest post...
    Are you indicating that the SSD was internally installed as a secondary drive in another PC and the system did not detect its existence?
    It wasn't listed in Device Manager nor was it listed in Disk Management? That's what you're indicating, yes?
    If that *is* the case, I would suggest you pursue a RMA with Samsung.
  9. It wasn't listed in Disk Manager BUT is was listed in Device Manager, just like on my computer.
  10. And did you run the Samsung Magician program in that PC where the SSD was connected as a secondary drive?
    If you didn't, you should. And determine if the SM program detects the SSD and reports its health.
