  1. disk partition not able to use


    So recently I noticed that only drive C: is showing in file explorer and there used to be 4 drives from C: to F: and I checked disk management, there was disk 0 with 900GB and disk 1 with 100GB. I'm sure that disk 1 is drive C but 100GB is not enough for me so how can I use those 900 GB? disk partition not able to use 22b9a936-0260-4a45-802a-4330a7930300?upload=true.png disk partition not able to use 4909bb4b-69de-4f1a-9aef-ea3364d724a4?upload=true.png

    W7 Hard drive partition issue

    to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

    - press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
    - diskpart <-- start the windows command line partition management tool
    - list disk <--- list the installed hdds in this computer for the next step
    - select disk 0 <- might have to replace 0 with the number of the correct disk
    - clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
    - create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
    - exit, exit to exit diskpart and the command prompt
    - click refresh in partition manager and select your newly created partition and install to that

    diskpart doesn't show disk

    Hey,

    I am trying to install Win10 on a mac book air.

    However the diskpart does not list the disk even after reformatting the partition as NTFS per suggestion.

    read through this solution but cannot move to step 1 listed in the solution by Ivan as that disk doesn't see that partition it was just able to reformat.

    Regards

  4. disk partition not able to use

    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 able to use :p

    side question, have you tried restarting the PC?
