I have aWD 3TB External drive that I've been using for a few months now. I recently moved it and and now it's moving extrememly slow. It's also slowing down the computers I plug it into. I tried checking for new drivers, I really don't want to have to format, and Itried unplugging and replugging. All that got me is the laptop takes forever to recognise it again. I tried running norton on it but norton finishes after claiming it scanned but the results stats it only scanned one file. I tried scanning for bad sectors but that was taking three days and only managed 1/10 of the way. I'm not techno savvy so I have no idea what else is in the card.
