Mike, If you want to test



If you want to test whether or not the hdd is your issue you could try copying some of the footage to your local hard drive and importing it into a new FCP project. If the problem persists it is an issue with the external hard drive. I don’t know if it is causing your problem, but in general I don’t know any professionals who recommend editing from a usb hard drive. While they are fine for storage, they aren’t really fast enough (at sustained speeds) for the editing process.
