Hi, I've been using my WD External Hard Drive with my Mac for a couple of months now, and this morning suddenly it won't show up. Not even in finder, or on Disk Utility. When I plug it in I can hear it start running, and also hear a scratching sound, but nothing happens. Finder > Preferences > General > Show Items on the Desktop > External disks is checked too. So now I'm at a complete loss about what to do. I have a lot of movies, pictures and important files in that drive. If the device cannot be used on Mac then is there any way for the files to be recovered? Thanks.
