Im about to partition my hard drive using BootCamp and i heard that doing this could possibly delete data off of my hard drive. I have a 500gb harddrive with about 190gb left of free space. I want to partition about 30 or 40gb to windows and leave the rest for OSX. Is there a chance that ill lose data when i partition or am i in the clear? And is 30-40gb enough for windows 7 and a couple of games (SW:TOR mainly).
