Upon further investigation, I found that when I boot off the Jaguar CD 
and run Disk Utility, the OS X boot partition is grayed out and will 
not mount.  When I run First Aid it says that the OS X partition has an 
"Invalid Extent Entry".  No matter how many times I click the Repair 
button, the error stays there.  Is my only option to wipe the partition 
clean?

Thanks,
