Hello, I just plugged my Western Digital external hard drive back into my desk top and the "file folder is empty." This is very distressing, as I had everyone for my school and business backed up on it. That's what it's for, right? I had it unplugged while I suffered from a couple of viruses. Monday a tech guy was able to clean them out. Now my external isn't working, but the computer recognizes used space on it. If there's space being used, how can it be empty? I know just enough about computers to get into trouble, so this has me pinned. Can someone please help me???
