Hey guys: I have a question when formatting a second hard drive I installed in my optical bay. My current setup is a SSD that I installed when I felt my computer lacking in speed (2009 MBP) and I deferred on a caddy at the time. Recently, I purchased the caddy and added my original HDD back. I would just wipe the drive but here is my dilemma, my older HDD has windows 7 which I occasionally use for work. Is there any way I can make my older HDD mac and SSD one while keeping my windows partition? Thanks in advance!
