Bad disk blocks?

Question:
What do you do when your computer has a bad disk block? Disk Utility.app returns the lovely:
Invalid sibling link

and promptly dies. Single user mode + fsck tells me that there's an I/O error on the disk, and then dies.

TechTool Pro tells me that I have a bad block.

Is the only way to fix this to back up stuff, format the disk with 0's, and assume that the system will write that bad block out of the safe-to-write-to-locations?
