install the drive into the pc being sure to attach the power cable and the data cable.
when you power back up and boot into windows it should ask you if ywant to initialize the drive - say yes.
If it didnt ask you to initialize the drive, go to disk manager (run diskmgmt.msc) and you will be able to initialize it there. what you have to do depends onif the drive is already partitioned or not...
after windows is ready to use the drive, you can set fraps to record there. It will probably be your d: or E: drive.
