Hello Brian, and thanks for your reply.
It appears my latest disk is 2008.5 and patches (Not yet reinstalled)
I do also have another larger external drive with around 300gb of free space but it is rather cluttered with folders I have saved over the last three years and thought it would be nice and tidy to just use a 40gb module I also have.

So I think I will try your advice and install to my C drive and then just move the bb file over to the small one first, I havent got involved with real tracks and drums much because my PC speaking system is only basic.

BTW I am now a Tyros2 owner with harddrive on that as well.

John
