Can you reformat a flash drive after writing an iso image to it?

Can you reformat a flash drive after writing an iso image to it?

I recently wrote an image to a 16gig drive, but now windows with only let me reformat it for 1gig of space.

Am I missing something? Shouldn't I be able to reformat it despite what is written on the drive?

  1. By writing an ISO you probably created a partition of the size of the ISO

    Go to Disk Management and delete the partition, then create a new partition using all the space
  2. You formatting it in NTFS?

    Try doing this:

    If you running windows 7/vista

    Start>RUN>CMD>enter

    type
    >diskpart
    >listdisk
    >Select Disk 1 (1 being the flash drive. Could be 2, could be 3.. i dont know. check the sizes if you are unsure, but be sure to select the right one)

    >clean
    >create partition primary
    >select partition 1
    >format fs=ntfs quick
    >assign
    >exit
    >exit

    This should format the flash drive correctly. Please remember to use the list disk to select the correct drive number. Drive 0 usually is C drive. find the drive that is the correct size of your flash drive, that should be it.
