Welcome TSchick.<br><br>When you upgraded to OSX 10.2.6, I'm assuming you had the FW harddrive plugged in? Did you unplug it at all?<br>I do know that firewire drives can be tricky as far as unplugging correctly and all that. I'm sure someone around here can help or confirm that you do need to send it off to WD.<br><br><br><br>
