Can't Remove UDF Partition From USB Drive

view full story

http://chakra-project.org – I've always had this problem after making a USB flash drive an installation medium for Chakra. After I'm done with it and want to return it back to it's original state there's always a UDF partition that is left over and no matter what I do I can't get rid of it since it is read-only apparently. I now have two thumb drives with un-removable partition and it's extremely annoying! I've tried everything even as far as killing the DOS File Table and replacing it with GUID, then back to DOS, but the partition is still there!Before it would always say it can't (HowTos)
