So after booting up this morning I find that one of my WD 2TB Green Drives has possibly failed and gives me this window containing (This volume does not contain a recognized file system. Please make sure that all the required file drivers are loaded and that the volume is not corrupted) when I try to access it. I have a little over 85% filled with movies. Is it in fact failed or is there some Magic I can use to re-gain the use of it ? Any help would be great.
