You probably have a different drive letter, I know at my school, all of them are 'E'. Just open my computer and it should say your drive letter next to removable device.
Because at my school they have stopped all USB activity since a hacking last year, and say you need to print out a project, but you don't want to ask a teacher for help, you could do this. Not rocket scientist, read the thread title. 'Can't access your flash drive @ school?'
Well, we made topics worth moving. Whats wrong dude? Honestly, if where in a password protected forum, and we post w/out the ability to delete it then it wouldn't be hard for staff to catch us, so obviously you wanted to get us in trouble?
