So I get a call from a person I use to work with and I've setup their home computer, etc etc, and she tells me "I've lost everything past C in my documents" ...hu?  Ok, she's moved them somewhere, no sweat.  I do a search across the system ...nothing.  Hmm, maybe she deleted it, ok fine, open up word, find a recent "lost" document and ...it opens.  With the recent updates.  Ooooooook.  I do a file, save as, point it to the desktop, bam, file appears.  Go to save as again, point it to my documents, it saves ...no file appears.  But if I make a file that starts with a, b or c ...it works. D-Z ...disappears INSTANTLY.

Now I'm confused.  I bust out the mad scandisk, and about 45 minutes later, scandisk says "I'm fine, no errors found" ...wait what?  Ok, windows is lying to me.  I plug in the drive to my laptop, run a scandisk on there and it says "hey I found stuff and fixed it!" sweet.  So I plug it back in and its time to move this stuff off the drive.  I go to copy it, and it promptly tells me there's not enough room on C.  Hmm, soooo how much room do we need (250g attached drive, 200g system drive so its possible) ...and I get this.

Yep, you see right, pentabytes.  Not mega, giga, tera ...penta.  12 of them.  I end up finding that _ONE FILE_ was causing this.  One. 

We discussed that we don't try to download the internet and she needs to show me the datacenter for the entire northern hemisphere thats hidden under her house.
