    How do I delete a primary partition


    I have a USB thumb drive that has 32GB imprinted on it but windows only sees 1 primary partition of 62MB. How can I delete this primary partition and get this thing back to a 32GB drive? Could there be hidden partitions?

    I seems to be formatted wrong for a memory stick, you have it as NTFS, here is my 8gb stick...fat 32 format

    I suggested re formatting because to extend it it should show unallocated space which his doesn't.

    I didn't notice that... thanx.
    But reformatting or deleting the partition won't help either (I think). Total physical disk size is 62MB in screenshot.

    Maybe reinitialize the usb disk will help?

    Possibly. Strange it only show 62mb. Is it as he asked hidden, or possible encrypted?

    In Elevated Command Prompt

    Code:
    diskpart
    list disk
    --disk 1 is the disk you want to fix? Be sure you use the correct number !! --
    select disk 1
    clean
    create partition primary
    exit
    Post disk management screenshot again

    Not hidden. You can put an encrypted file system in a container that is actually a fiel in a partition. Or encrypt a whole partition. But anyway... the partition size shows correct in disk manager. It's just end-sector minus startsector.

    Don't know where the really last sector on disk is stored... so I don't know it computes the disksize.
    Even an totally cleaned disk has a disksize!! Maybe stored in firmware(?)

    I know we're not talking about sectors here becuase it's usb flash stick, but actually it's the same.
