I put Jolicloud on a pendrive to install it to my laptop, tried it out, didn't like it, and installed ubuntu with a CD instead. Now I want to use my pendrive for storage, so I popped it in, loaded up Gparted and formatted the drive.
Now, when I pop the pendrive into my laptop, Ubuntu thinks that Jolicloud is still on it, when Gparted says there are no partitions on the pendrive.
Screenshot: What's going on, here? How can I properly format the pendrive?
