Subject: Bug in Parted

Hello, I was trying to use Parted to resize a partition on an USB thumb drive. More precisely the partition exceeded the size of the disk. Below you can find the complete output of the session and yet below the output of the command "parted DEVICE unit co print unit s print" as requested.
