You're right, this is problematic especially in Linux tools like GParted -  
it will try to format the drive to 4x larger than it actually is. While  
this may not be the source of the problems GParted has with USB sticks  
containing dd'd Fedora ISOs, the tool is just not able to format them  
correctly.

The safest bet when restoring the drives manually is to use your  
platform's variant of writing the partition table with zeros and reinsert  
the drive. FMW does handle this without the need to reinsert the drive  
though (also you're right this should be advertised a bit better when  
you're writing the iso - I actually had the message in there but I, uh,  
sort of got rid of it and it never occured to me it's missing).
