To cut a long story short, I have a Crucial m500 that has an OS (W7) installed on it and some other stuff, that I want to turn into a drive to store my Steam games on. I've read up on how to do this and I'm getting contradictory information and I trust OCUK to give me the right answer 
This method -- quick format using W7 Disk Management -- seems like the simplest option:

But other sources have said do a secure erase using software taken from the manufacturers website, because that will lead to better performance from the drive than if it's quick formatted. I can't find anything on their website anyway though.
