Ok, so this is a strange problem. When I first installed mac (Snow Leopard with myHack dual-boot w/ Win7), I could see my two windows formatted drive partitions. In my volumes menu, it showed my mac partition and the two windows partitions. Now, for some reason, when I boot into Mac, the only drive that shows up is my OSX partition. Where did the windows partitions go? I need them back. Thanks in advance for any help.

You can check settings in Finder Preferences.
