which format to do use to format an external HD so it can be read with PC and MAc

    For maximum compatibility, FAT32 from Mac OS X or exFAT from Windows. Drives formatted as NTFS can be read on the Mac but not written to.


    If you're going to be using it as a network share, NTFS if it'll be connected to a PC or Mac OS Extended (Journaled) if it'll be connected to a Mac or AirPort base station.
