  1. Disk partition not showing up in disk management


    I installed a windows 10 update yesterday and now I have lost my D and E drive and all of the data that was on there. When I go into disk management the only drive that shows up is the C drive and 3 others that are called disk 0 partition 1, 4 and 5. When I go into file explorer I only see the C and my DVD drive but that's it. When I put my laptop in sleep mode and woke it up the next morning the drives were back and they worked fine until a windows notification said that a drive is broken and can be fixed. It prompted me to restart my laptop and once I did the drives were gone.

    :)

  2. Disk management console view is not up-to-date

    i dont know how to fix your disk management, but i can fix your partition problems...




    open up Command Prompt with admin rights. (Right click, run as admin)


    enter in
    DISKPART
    list disk

    then find the Disk number for your Raid array... lets call it number 7 ( you can tell what disk is what by the total size)
    type in

    Select Disk 7
    List Partition (will give you a list of all the partitions..)
    Select Partition 1 (im assuming you only have 1 partition on Disk 7) repeat this step if you have more partitions.
    ASSIGN


    that should get the array up and running ready to use.


    EDITED.

    any problems, post back ^^


    Still EDITING *Stick Out Tongue Disk partition not showing up in disk management :p

    side question, have you tried restarting the PC?
     
  3. Disk Management

    Hi Keith,

    Thanks for providing the detail that was requested previously. Since the disk management screen that you saw is showing greyed out options, we suggest that you follow the steps below to change the partition type of your internal drive:

    • Open Disk Management then right click the partition on the disk you want to covert and select Delete Volume.
    • Once you complete the process you will see the whole disk shown as two separate unallocated spaces. Right-click the disk and select Convert to GPT disk.

    After the conversion, you will be able to use the whole disk and then you can create new separate partitions.

    We look forward to your response to our queries.

    Disk partition not showing up in disk management

    Hard disk partition not showing up.

    Hi Muhammad,



    Thank you for writing to Microsoft Community Forums.



    This can happen if the Hard-disk drivers are not up-to date. I would suggest you to update the hard disk drivers first. To update the drivers, please follow the steps mentioned below:

    1. Open Device manager.
    2. Then Expand “Disk drives”.
    3. Then Right click on the Hard-disk listed under this category.
    4. Then click on Update drivers.
    5. Alternatively you can also try to update the drivers from manufacturer’s website.

    Once the hard-disk drivers are updated, you will need to allocate the last partition (it is not allocated according to the screenshot) and you will be able to view the partition.



    Also note that sometimes the hard disk partitions/drives might be hidden in This PC or My Computer window due to a Registry key. If a DWORD with the name NoViewOnDrive or NoDrives is present under following key in Registry Editor:

    HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer

    Delete the DWORD and your drives will become visible in My Computer window.



    Hope this helps.
