I think this fucks up some of the internal hardware. When I plug my external hard drives into this, there are always errors transferring footage, opening footage, etc. However, when I use an adapter that I bought from the apple store, it works just fine - no issues. I've had broken hard drives due to this thing - it just messes up something internal and won't read correctly. I still kept it for the HDMI plug in though.
