Problem Updating Classmate

Hello,
I was recently trying to update my team’s classmate; I plug the E09 USB thing in and press F11 to bring up the boot menu and go into “Generic Flash Disk”, but after that it says “Disk read error occurred” :ahh: . Has anyone else had this problem, and is there a fix, or will I have to get a flashdrive?:confused:
