Need help quick - protected folders

I have to get these .psd files copied to an external hard drive, really fast.
But when I try to copy the files over to it, it says something like; “the medium is protected”. I can’t create folders or anything on it. So I have to remove the protection somehow. How do I do that?

I tried to right click on it, and search through the properties and stuff, but I didn’t find anything.

Also… if anyone know of an online file uploader thing (that accepts .psd’s), that I can use instead, that would be nice! I tried to send the files by mail, but hotmail is focked up! Of course when I need it the most:-/
