Hi there, I recently upgrading my 2012 mid MBP by removing the optical drive bay replacing it with the old HDD and replacing this with an SSD. So my system runs an SSD + HDD. Due to personal reasons I wanted to try using Win10 on my machine. I have been able to get it up and running through bootcamp, partitioned my SSD (240gb) into 40 for OS X and 200GB for Windows. The question I asking is how can i use my HDD whilst using windows. Bare in mind I dont intend on using it for storage on OS X at all. Sorry if the answer is obvious.
