Hello, I have a few directories on my external firewire drive that I get an "permissions" error whenever I copy a file to. For example, when I copy a file from my mac to one of these directories on the firewire drive, it pops up a dialog and tells me the following: The item [filename] could not be moved because [directoryname] could not be modified. Then it gives me the option to authenticate. Once I do, the file copies fine but when I try to copy another file it happens again. Is this a permissions problem? How can I repair permissions on an external firewire drive. I thought diskutility can only repair permissions on a boot volume, which my drive is not. Any help greatly appreciated. I've done a search but found no satisfactory solution.
