First erase the drive in Disk Utility. When you then use it for Time Machine, it should automatically format it. However, understand that Time Machine uses the GUID Partition scheme and Mac OS Extended Journaling as its format. This is a Mac specific format and, thus, will not work in Windows. You can partition the drive so you can use one partition for the Time Machine backup and the other for other data, but you should do this prior to employing Time Machine.
