problem with seagate external harddrive "CNID database" error
I have a seagate external drive (3TB) that has worked fine over my apple airport extreme network for a while. All of the sudden I cannot access it anymore and I get the following error: "Message from server 'goflexhome' Something wrong with the volume's CNID DB, using temporary CNID instead. Check server messages for details. Switching to read-only mode." What does this mean? check what server messages? Can someone please translate this for me? It makes no sense. Thanks!
