    One partition suddenly inaccessible [​IMG]


    diskmgmt.msc also showed it to be healthy.

    diskmgmt.msc's properties was the only thing that revealed that all permissions were gone!.

    I was able to create ("Add") permissions in the properties' Security tap. Problem solved.

    I am writing to ask whether anyone ever has encountered disappearance of all permissions
    to a partition. I never had.

    :)

    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

  3. URGENT HELP NEEDED! HDD suddenly became blank!

    Hey there, @Shamonto Hasan Easha!

    I'd try re-plugging the hard drive and checking if the cable is damaged. I'd also suggest to try plugging the drive in another computer and see if it gets recognized properly there. Is it a IDE or SATA drive you're using?
    If the drive is unallocated, this means that the partition has been lost after the power went down.
    Check out this thread for more ideas on how to solve the issue. There are some detailed steps there that might be useful for you:

    Hope this helped.

    BSOD - Inaccessible Boot Device

    The reset save files equivalent if successful should be the quickest method to get you backup and running.

    The backup files then clean install is the best option as you fix many problems and start fresh.

    The command prompt commands are all trial and error.
