When you are copying complete image to flash drive, you don't need to
format it. (useless action, you will overwrite it later)

Not sure for centos images (I think older ones are not compatible to be
directly copied to device, and don't know for new ones >=7. But fedora
should work fine, and when you do it, you don't copy your image to the
partition, but to the device, so of=/dev/sdx1 is wrong, (1,2,3.... ) is
a partition number. 
You need something like this 
# dd if=<fedora_iso_image> of=/dev/sdx  (where X can be a,b,c,...)
Be careful with this method it will overwrite device with data of size
of the image ...

And always when you download ISO images verify them
