So the post didnt let me put my own pictures so those are not my but they have the same message. Doest the name matter cause I can look up the correct name. Its formatted on mac. I tried with my friend to erase everything on windows software and it said it had write protection (didnt let me erase) and im not too sure if thats the problem.
