Someone may have posted about this before, but I couldn't find anything about it.  I found out about a utility that lets you copy games on your Steam account across multiple partition or hard drives.  I test it with Super Meat Boy since I figured if it jacked something up it's a fairly small game, so it would be easy to re-download.  Worked great tho, copied it from my 1TB Steam-only drive over to my 64GB SSD boot drive.  My plan is to use this to copy over a game that I want to play for significant amount of times to improve load times with the SSD, and then copy it back over to the original Steam directory once I'm done playing it. 
 
Anyway, just thought I'd throw this out there in case it helps someone else.
 

Whoa, yeh I probably should have used this. I completely messed up my installs of all the source games recently. Not sure what I did differently I would manually copy out the games I wasn't playing. Went to put them all back a few week ago and I Borked it all up.
