I teach a video class at SWHS and we are having a big problem that I have never encountered before. 4 Canon ZR830 cams and a GL2 have lost the function to transfer data through the ieee firewire port. All worked, then just started going down. The computer port works fine. I've tested the ports with external HD's and hubs and all work. The camera works great. WHen we connect the firewire cable to the camera and turn it on, nothing happens on the computer. The software says it is not detected.
The computers are AMD quad 4500, 2 gb memory, 512gb video cards, 4 ieee ports on each computer. None of the ports work with the cameras. Has anyone else gone through this? Are the ports on the cameras all bad??? How?? Kids are rough, but not that rough with gear. Any help is greatly appreciated. And yes, we have tried different cables.
