Comment 199 for bug 1325801

Yes ndorf, this is the intended behaviour now. The Ubuntu Startup Disk Creator is *cloning* the iso file, which is a much more robust process that the previous method.

The easiest method to restore the pendrive to a 'normal' data drive (for storage and transfer of files) is to create a new partition table and file system, for example with mkusb according to the following link

or with gparted according to the following link
