I just plugged my new HD into my mac w/USB and it worked fine but FW800 seems to be not responding. I tried front and back ports but got nothing. I hope its not the cable because then I gotta spend more money :/ and wait again.

Try
- Shutting down and restarting from cold with the drive plugged in. Or if its got a copy of OSX try booting from it.
- Is it a Mac Pro or G5? Does the drive show mounted in the Disk Utility?
- DOes the Firewire Bus appear in System info panel?
- A FW 400 cable instead. or the other FW800 port if its a Mac Pro.
- If the firewire bus is there but disk doesnt mount try reseting the PMU (SMC in intel macs) sometimes the Firewire just needs a reset.
