Disk Utility Crashed during an "erase free space" and now no space exists

Question

So i have no idea how to recover my space after disk utility crashed while I was out today, All I know is I had close to two hundred gigs freed that I wanted to wipe clean after resetting some things in various applications.
I figure I could go find the offending file through some unix-fu. Boy was I wrong
udo find / -type f -size +300000k -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'
/System/Library/Speech/Voices/Alex.SpeechVoice/Contents/Resources/PCMWave: 382M
/Users/vahtryn/lotusnotes851_macCZ5S6EN.dmg: 402M
Thats all I got for searching for any file sized 300 meg or more. So, what's the deal? How can I recover this space if I can't find the EFTFile1.sparseimage that's supposed to be created?
I read elsewhere it should be here: ls -lh /var/root/Library/Caches/TemporaryItems
ls: /var/root/Library/Caches/TemporaryItems: No such file or directory
Not on my SL install.

Okay, found a solution. Posting it for others who experience this problem.
1. Restart your computer
2. When your computer is completely started back up, check your trash can. If there are recovered files in there, empty trash.
3. If no files are in there, delete a file you don't need, or make a screen shot of something and delete it. Then empty trash.
After doing the above, temporary files were erased. At least that's what worked for me.
Finally: if you haven't done so already, back up your entire system, so in the event you have a complete crash, you will have a back up.
