I am new to mac and I just bought a new 27" mac. I am using Parallels desktop 9 software to run my windows based software. Also I have 2 external hard drives, drive E: for all my important save stuff and Drive T: for Time Machine. I am not sure what the problem i am having is coming from. When I open Drive E: and try to create a New Folder a error window comes up (see attachment). How do I fix this problem? Thanks funnnyfarm
