I am an inexperienced MAC user. I have a 1.5 terrabyte Freeagent drive. When i get info it show readonly permissions and nothing else. How can I change the permissions so they are just like my Imac internal drive?
It's probably formatted as NTFS, which is a Windows format and can only be read by Mac OS X without extra software. If you don't need to access the contents of the drive on Windows, you could back up the contents and re-format to the native Mac format "Mac OS Extended (Journaled)" it using Disk Utility.app.
