I Have a 400gb Hard drive partitioned into 2 parts. One is the 20gb C: partition were Windows XP (home) and some other programs are installed. The other is the 380GB E: partition were all my media, games and other large software apps are installed. In the next month i am either going to install Vista or upgrade to a 64 bit version of windows XP. Will i still be able to use my apps on the E: drive when i install the new OS onto C: (Assuming that the C Drive is Formatted)?
