I’ve tried everything from simple restore to full restore. My firmware is up-to-date. I’ve confirmed the external drive (WD 1TB Passport drive) has correct disk permissions and has no problems. I’m running iOS 10.9 on a MB Air. I have a Belkin router with uPnP enabled. I called tech support last night and got no help just, “Looks like you’ve tried everything.” The performance is fine until I connect the secondary drive. Then I can’t do almost anything. The web interface times out before connecting and the Finder window takes 30-60 seconds to switch between folders.
Is anyone else facing this issue or do I have a lemon?
