I have Mac Book Pro with most updated OS. I have Belkin Router Monitor with most updated firmware. I have external hard drive with MS DOT (FAT) format. I would like to use my router for home network so I have attached external hard drive to my belkin router to share data with my Macbook and my Samsung TV. I noticed that I could detect my external drive in my mac book and my Samsung TV (I could open the files from my hard drive and view it in my mac book and TV). However, when I try to copy data from my mc book to my external drive (which is connect with the router) it shows me the message Items cant be copied to XX (my hard drive name) because you dont have permission to read them. I have also seen the permission request by attaching external hard drive with my Mac. It shows me that I have read and write permission. I am looking forward for some solution so I can copy data to my external hard drive when it is attached with my router. Please help me.
