hey guys, just got a quick dilema here... I have a external SATA HD that i had with my desktop with my old files in it. Its plug and play with any PC or mac and i can access the files fine. I can read files but it wont let me write. I cant delete or write new media on it. Any suggestions on what might be causing this? It might be simple but ive looked in the preferences and call me stupid but i just cant see how to change this option. any help would be greatly appreciated.
