I found this link above while searching for a solution. I am trying it right now:
"If you have a Windows partition on the same drive, sometimes stray files
get placed on the Mac side.
Try emptying the recycle bin, but first run the Check Disk Utility for
Windows hard drives. (Open My Computer, right click on the 'C' drive,
and click properties. Click on the tools tab, then Check Now. Make sure
that there is a check in the box that says "Automatically fix file
system errors." Then you will be prompted to reboot. Check Disk will run
on reboot.)"
I believe this problem is related either to BootCamp, Parallels, or TechTool Pro's emergency disk. But as I am running this disk check within windows, it is deleting a to of files:
"Deleting an index entry with ID 2353 from index $SDH of file 9..." etc.
We'll see if that fixes it.
