Set up is a Lombard, FireWire2Go, Maxtor 40 Gig HD, MacOS 9.1. I use CopyAgent to back up my HD to the Maxtor. At the beginning of the copying, it will get consistent messages saying the the FireWire device has been disconnected. I have to disconnect/reconnect the power to the Maxtor to resume. It will do that at first then as the copying continues it will happen less. Any ideas?
