SOLUTION:

1. Turn off the computer
   
2. Hold down Option+Command+P+R and turn on the computer. This is the parameter RAM reset key combination.
   
3. You will hear the Mac "ding." Continue to hold down this key combination until you hear four "ding" sounds. This zaps the PRAM
   
4. Immediately after the fourth "ding," hold down Option+Command+O+F to boot into open firmware.
   
5. Type the reset-nvram and hit return, then type reset-all and hit return.
   
6. Now, hold down Commad-Option-S to boot into the command line in single-user mode
   
7. Type fsck -y and hit return. This will run a file system check. My check resulted in two errors in the multi-linked files.
   
8. If you get any sort of error, keep running fsck -y until the check returns no errors on the volume. If you see everything is OK, proceed to the next step.
