While your OS usually makes the choice of hard drive format for you ahead of time, you can choose which format when you're re-formatting a drive, particularly an external drive. If you need the drive for a Windows-only environment, NTFS is the best choice. If you need to exchange files (even occasionally) with a non-Windows system like a Mac or Linux box, then FAT32 will give you less agita, as long as your file sizes are smaller than 4GB.
