As a matter of fact, it wasn't plugged in. Mac OS 10.2.5 was having problems with hub drives and so I was getting kernel errors and shutdowns. I called AppleCare and they told me to disconnect all my firewire drives and USB hub devices....which I did. The next day I upgraded to 10.2.6 after hearing about the USB hub problems. I tried to plug back in my FireWire drive and that's when it wouldn't mount. Sigh.<br><br>
