I found this online:

	This error message means, in English:
	"You have files that are stored fragmented--one file is in many  
places on your
	disk. one of those files has a bad entry in the part of the  
directory that
	keeps track of fragmented files. i can't locate all the parts of  
that file."

	TechTool Pro can usually fix this problem; DiskWarrior can usually  
fix it too.

Since DiskWarrior didn't work, the obvious thing to do is boot from  
the install CD or another drive and try to fix the troubled drive  
with Drive Utility. Even if that doesn't work you might be able to  
back this drive up before reinstalling.
