When I click on the upper "FireWire Bus," it says in the lower window: "Maximum speed: Up to 400 Mb/sec.", and that's all.
It strikes me that one of these "FireWire buses" might be a PCI-X card I installed that provides some extra USB and two FW ports.
Yes, one of the buses is the PCI card, that's the one that says "Maximum speed: Up to 400 Mb/sec". The built-in bus of the G5 should say "Maximum Speed: Up to 800 Mb/sec" when nothing is plugged in to it.
The lower "FireWire Bus" has a little disclosure triangle, and when I it, it lists two "Unknown Devices." If I click on either of those two "Unknown Devices" it says this in the lower window: "Unknown Device. Manufacturer Unknown. Model Unknown. GUID 0X0. Max speed: up too 800 mb/sec. Connection speed unknown."
Humm. This isn't good. Normally it should identify the device, and since OWC enclosures all use Oxford chipsets AFAIK, these should be very explicitly identified.
So now there are a couple things to check. First would be the cable itself. Are you certain the cable is good? Second, it's possible there's a power supply issue, but perhaps that's too much for you to check. A very unlikely third possibility is that the firmware of the enclosure has become corrupted, but that's VERY unlikely. Most of the newer enclosures that have FW800 don't have any firmware updates AFAIK, so I think it's starting to look like your enclosure either has a bad cable, a bad power supply, or a bad Firewire bridge. The odds are high that the HD inside the enclosure is fine. If your G5 only has a single HD installed, you can remove the HD from the enclosure and add it into the G5 without needing any extra accessories other than the tools (a phillips screwdriver to add the HD to a G5, perhaps something more to remove the HD from the enclosure). It's a simple job to remove the HD, basically open the enclosure, unscrew the HD (four screws max) and unplug the two cables. To add the HD to the G5 there are extra HD mounting screws on the plastic wall on the left-hand side of the HD area of the G5. The HD slides into plastic rails using the hemi-spherical rubberized screws as guides along the lower edge of the HD. Slide the HD in and attach the two cables that slide out from above. It's really easy. This will let you know if the HD is good. You can run S.M.A.R.T. tests on the HD or any other utilities, but I'm guessing it's fine. The enclosure is another matter, and you may or may not be able to fix it, depending upon what the problem is.
