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?

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

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.
