I've been messing with this new SSD for a few weeks now trying to work out what's causing it to crash, but before I finally give up on this Vertex 3 and send it back, I'd like to try and clone the original HDD onto it, Just in case I've missed some random driver not available on the MSI site. 
Are there any other issues doing this is going to cause?
