I prefer two partitions per drive, and for these reasons:
1.) It is far easier to image the primary active partition that contains the operating system with this method. Many imaging programs function best during the image creation by first burning to a separate partition, instead of directly to CD. Drive Image 5.0 is a specific example.
2.) If a hard drive begins to fail, it is sometimes possible to save a certain amount of files if they are in a another partition on the drive. This is not usually possible if the drive fails, and has been set up with one large partition.
3.) Creating additional partitions can also keep large programs separate from the operating system, such as with large multimedia applications.
4.) When using NTFS, having your paging file in a small, separate partition can keep the file from splitting into multiple fragments. And this can also allow you, (with a second hard drive) to place the file at the top of the slaved drive for slightly higher performance. This considerably reduces the amount of time needed for the occasional boot-time defragmentation in Win2K and WinXP. Reducing the paging file fragments can be the most lengthy part of this kind of defragmentation.
5.) With larger hard drives, and the FAT32 file system, having smaller, multiple partitions will reduce the size of the clusters, thus allowing less wasted slack space.
Note: This isn't necessary with NTFS 5.0, as the cluster size never increases over 4K.
Some people create more than one partition per drive strictly as an organizational tool, but as you can see, there other valid reasons why this can be useful.
