I am using OS 9.2.2 with Retrospect 5.0.205. I have a LaCie Firewire/USB combo AIT tape drive. Up until last Thursday, the machine worked consistently. Now, I get the "Device not found" message on any system I attempt to use it on. It appears to show up in the System Profiler but, Retrospect fails to recognize it. Any ideas. Thanks Dan
