I've tried deleting the directory inside /media and then creating it again, naming it, then giving that directory full permissions. However, this didn't work and I can not understand why it has suddenly stopped letting me write to the drives, and I can't figure out how to solve it. If anyone could help that'll be great! Let me know if you need me to post any output from the terminal, I'm quite a Linux novice so I'll need my hand held through what code to use. Many thanks in advance!
