Windows 10: Win 10 upgrade will no longer recognize 2nd internal drive.

  1.    07 Nov 2017 #1

    Win 10 upgrade will no longer recognize 2nd internal drive.

    I upgraded my Dell Insperion from Win 7-64 to Win 10 home 64, and it no longer sees my 2nd internal hard drive. I tried a scan in device manager but it did not help. Any advice?

    Hi there. Is it recognized in > Hold Windows key then press x > Choose Disk Management?

    It may report it needs to be initialized. If so, please report that first. Do not perform yet.

    Did you make a backup before upgrade by any chance?

    There are 4 methods to identify the internal drive and the first 3 depend on functioning Windows operating system:
    1) disk management
    2) device manager > disk drives
    3) file explorer > this PC
    4) BIOS
    If you do not see the drive using steps 1 - 3 using windows check the bios to see if the drive is identified.

    Run the Dell diagnostics on you computer and post images of the result into the thread:

    As stated, Restart the computer and press F2 to enter Setup (Bios) Here, on the left panel under System Information and Hard Disk Drives, it should show your secondary drive. If it is not listed in the Bios, then it won't show up anywhere else. Be sure the drive data cable is plugged in tightly to the back of the drive and into the Motherboard. Make sure the Power Plug from the PSU is plugged in tightly. Put your Ear next to the drive in question when you start it up, does it sound like it's spinning up or is it cold, no power? If the later it has failed. You can try replacing the data cable and try a different power plug.
    If the drive is listed in the Bios, then boot into Windows. Press the Win key+X and choose Disk Management. In the lower pane, on the left panel, under Disk # does it say your drive is Not Initialized? or in the right panel, does it say your drive is Unallocated Space?

    I found a simple solution. The Dell BIOS system needed to be updated after the windows 10 installation. Dell has a "detector" to download, it scans then takes you back to Dells web site and shows you which updates you need. Just click download and install. The whole thing took 10 minutes and now I have both drives showing again. Drivers & Downloads | Dell US
