    Completely format bootable USB flash drive


    Hi
    How to completely format a bootable USB flash drive because I found there's a partition on the flash drive named "UEFI_NTFS" (EFI > Boot & Rufus folders with .efi files inside) that cannot be formatted.
    My other bootable USB with MBR partition can be fully formatted.
    I still keep the Win10 iso file & Rufus if needed.

    Thanks

    :)

    USB Flash drive made bootable

    Hi Nelson,

    Check if there is any slide switch on the side that provides write protection. It show's a closed and open lock on each side. We suggest to follow these steps below:

    • Insert the USB flash drive into the USB port.
    • Click Start, type devmgmt.msc in the Search textbox and press Enter.
    • Find Disk Drives and expand it.
    • Find the USB flash drive you want to format, and double-click it. It opens the
      Properties dialog box.
    • Click Policies tab.
    • By default, the Optimize for quick removal option selected, switch it to Optimize for performance and then press
      OK.
    • Now open Computer. Right click on the USB Flash Drive and select Format. The Format dialog box now appears.
    • Select NTFS in the File System field.
    • Press Start and wait while the process will be completed.

    You can also connect the USB drive on a different computer and try formatting.

    Let us know how it goes.

    Completely format bootable USB flash drive

    USB Flash Drive saying not formatted..?

    Hi,

    I have a Memorex Poker Chip USB Flash Drive 1GB, and It shows up fine on one PC as "Poker Chip" in explore, and I can transfer files... but on my other PC (the one I'm on now..specs in profile) it's listed only as H: Removable Disk, and when I click on it, it says: "The Device is not formatted, would you like to format it now? (Y/N). Why would it be recognized on one PC, but the not the other? How come the other PC didn't need it formatted? When I click yes to format it, it says: "Windows was unable to complete the format"

    I went to the BIOS and USB 2.0 is enabled. And Device Manager does list it as a Memorex Poker Chip..
