Hi, so I'm trying to troubleshoot my gf's external hard drive and I'm looking for some advice or suggestions on things to try. Basic specs: Age: 1 -2 years Capacity: 500gb Interface: USB 2.0 Brand: Western Digital She was just transferring files to it and suddenly it became super slow. It's sporadic, sometimes it will transfer files quickly at normal speeds, other times it will take hours to transfer a few hundred MB. The USB cable is loose and tends to get disconnected easily, so this may be a factor. What are some things I can do to narrow down what the problem is, and possible solve it? How can I rule out a hardware issue v.s. some kind of file system error? Thanks.
