No idea, installing? Using?
I am just about in the same boat with Maschine....
Make sure you don't drop, jar, or handle roughly, that drive, because it will stop working. The best thing to do is install it onto a drive that you will use, and then also make a copy of it onto another drive as a back up. There is a lot of useful stuff on there as well as a lot of stuff you won't use. Just depends on what kind of stuff you do. Also plan on spending a significant amount of time installing the new updates that have came out since it was manufactured.
