i have an external hard drive which i use to backup data. i.e. music, movies, pictures etc.
i have just purchased an imac and when the hard drive is plugged into the imac one folder shows up as locked. this means i cannot add new files or delete old files.
i plugged the same drive into my laptop running vista and i can make changes, however when i right click the folder in question and click properties it shows read only. i have un-ticked the read only part and applied changes but it still wont work on my mac.
any help is appreciated.
