[QUOTE="ndeep, post: 1398386, member: 249969"] Thanks HarryB! To clarify- The WD is formatted as MOSX Extended (Journaled) - Apple Partition Map The SeaGate is MOSX Extended (Journaled) - GUID I'm copying from the SeaGate to the WD. While the output ports on these drives are USB3, I'm using the included cables that are standard USB2.0 on one end. The problem is occurring both when using a hub and when connecting both external drives directly to the USB ports on the MBP. I chose to re-format the SeaGate with the Apple Partition Map just to see if it performed differently than the WD with the GUID. So far it's working, but I'm not sure that my choice of APM over GUID is the reason why... Both of these drives are meant to be a file archive, but I do want to access audio and video files from them regularly. Ideally, only one will be connected at a time, with the other completely disconnected and stored away safely in case of a failure of the currently connected drive. Again, thanks for the tip Harry - I'm reading the article you recommended next, and will continue to report on my progress. Anyone else has any ideas, please do chime in! [/QUOTE]
