Here are a few partition scheme examples:

1. Let's say you have a 40GB drive and plan on running only one operating system. You could divide the drive into two partitions, 5GB and 35GB. You would put the operating system on the first 5GB partition and everything else (mp3's, video files, photos etc), on the second 35GB partition.

2. Let's say you have a 30GB drive and want to run two operating systems, each on its own partition. Divide the hard drive into four partitions. 4GB for the first, 4GB for the second, 1.5GB for the third and 20.5GB for the last partition. You could put one operating system on the first partition (4GB) and the other on the second partition (4GB), the third partition could be a Download partition and the fourth would be for everything else. In this case both operating systems would exist within the first 8GB, even though they are on two partitions.

3. Lets say you have a 60BG hard drive and you are planning to have two operating systems. You could partition your new hard drive into three partitions. 3GB for the first, 5GB for the second and 52GB for the third. The first partition of 3GB is for OS 9.2, the second partition of 5GB is for OS X then the last partition of 52GB (approx..) would be for everything else. Again, both OS's sould exist within the first 8GB.

The possibilities are many. The only restriction is there can be no more than eight different partitions. If you would like to read the actual procedure, go to Formatting & Partitioning. This page will describe the step by step procedure for formatting & partitioning using the 'Drive Setup' application. Here is a link to the page where you can see some of the windows from the 'Drive Setup' application. Remember, this actual procedure is done after you install your new hard drive.
