How few?

How did you make that determination? IME, writing an iso to a USB stick can take
an obscene length of time, finishing *long* after the command prompt returns if
you have a lot of RAM to read the iso into before the stick can be written to.
Was the stick's activity LED off before you tried accessing it or rebooting?

Maybe the bad magic number resulted from writing less than the whole iso file to
the stick?....
