    D-drive missing after Windows Quality Update


    I have a Dell G7 laptop with Win10 on the C-drive solid-state drive, SSD and a separate D-drive spinning HDD for data, files, etc. The C-drive is nearly full, so all of my documents are on the D-drive. Last night the laptop did a forced reboot after installing the KB5001028 quality update, and suddenly the D-drive disappeared. I tried uninstalling the update, ran the Windows troubleshooter, scandisk, device manager, disk management, etc., no joy. The drive literally disappeared from the OS - it's not in device manager, disk management, I can't find it in a command prompt or powershell. I checked the BIOS and made sure the D-drive was not disabled somehow - both Disk0 C-drive and Disk1 D-drive are enabled in BIOS, but the D-drive has just vanished from within the OS - only Disk0 appears in any of the control panel widgets. I even took the back off the laptop to check cable connections, etc., but everything looked fine and still no D-drive after putting it back together.


    Earlier today I connected an external USB hard drive to the laptop - this drive was mapped as D. Sometime later the old D-drive suddenly re-appeared in Windows Explorer as the E-drive, with all files apparently intact. I disconnected the external drive and re-installed the quality update and rebooted - the drive was still there, now mapped as the E-drive. But then a little while later the E-drive disappeared again.


    I'm completely baffled - I guess it *could* be some intermittent failure in the drive hardware, but I can't even run a diagnostic on it since it's just gone. It doesn't show up in device manager, so i can't update or re-install the driver. In disk management I tried to rescan for drives but it doesn't appear - only Disk0 shows up. I'm suspicious of the Windows update - I've checked online but found no reports of problems with this particular update.

    Why would the drive just disappear completely from the OS, and then reappear? One last thing - the update originally failed to install because the C-drive was too full, but it forced a reboot anyway. Could that have caused the issue somehow?

    :)

    Hi,

    Based on the details you have provided us, it appears that there might be some corrupted contents on the said partition. We can also consider that this is caused by a virus.

    For us to check if a certain virus is hiding your files, kindly follow the steps below:

    • Type Command prompt in the search bar.
    • Type-in the following command:

      attrib -h -r -s /s /d D:\*.*
    • Press Enter to execute the command.

    If you think that there is nothing important stored in it, then we suggest that you reformat your D drive so that you can use the free space for important files.
