Recovering unallocated space of a USB flash drive.

Today I played with the latest SUSE Linux Live. I had not have a DVD drive and used USB flash drive instead. I wanted to reformat my flash drive, but suddenly found it that it had not been possible. The most of the disk space had been unallocated, and my Windows 8 did not allow me to use it.
