Hi Bill Holton,
You can repartition an external drive, and create both a fat32 windows 
partition and a mac os 10 extended journaled one with mac disk utility. You can 
then use the fat32 partition to share data between windows and the mac, and you 
can use the os10 partition to maintain a backup of everything on your mac. 
Let's begin by looking at how to resize your macintosh hd partition and have a 
sandbox beside it.
It involves a few steps which I'll describe below. Not key by key though. I'll 
assume that you have some mac knowledge, but just don't know where to go yet, 
and in what order. Here you go.

First open disk utility, to carefully inspect your current configuration so 
that you know what you will be changing..
To do this, Go into the finder, say, your desktop, and press command shift u 
from there. This will open your utilities folder. Here, find disk utility dot 
app, and open it.
In the disk table on the left, interact, and look at your current disk 
configuration. You need to know a few things before you go do something here. A 
disk is just a disk, and you cannot use it directly. It needs to have a 
partition to hold the file system, inside of which you can store files. There 
are many file systems, one of them is fat32, and another is mac os10 extended 
journaled. A filesystem lives inside a partition, so the partition is the 
container for the file system on the disk. From the disk perspective, you first 
have an empty disk. Then you create a partition on the disk, spanning all or 
only part of the disk size. As you are creating the new partition, you must 
choose which file system is going to live inside it, because The partition must 
be formatted for use with the type of file system that you want to use. In 
other words, the way you format your partition, becomes a property of the 
partition. So, on your external usb drive, you can have a fat32 partition, and 
a mac os10 partition, and you can have 2 separate mac os 10 extended journaled 
partitions on your internal mac hard drive. In both cases, You then just 
allocate one bit to the first partition, and the rest of the disk space to the 
other. You do this by setting the size text fields inside disk utility. See 
below.

Once inside disk utility on the mac, you will see your hard disk as the brand 
of physical disk inside the machine, for example Hitachi 500gb. This item in 
the disk table is usually expanded, meaning there can be something inside it. 
And indeed, there is. It's your macintosh hd partition, formatted as mac os10 
extended journaled, with a size of your entire disk.

What you want to have, is not 1 big partition of 500 or 320 gb, what have you, 
but you would like to shrink the os10 partition and make it 20 gb smaller. You 
will use these 20 gigabytes for the sandbox partition. This can be done, but it 
can't be done non-destructively. In other words: resizing your partitions with 
disk utility is indeed destructive, because it will destroy all data on the 
disk. In all partitions.

What you can do is back up everything, then recreate your macintosh hd 
partition 20 gb smaller, create a sandbocx partition beside it, and then 
restore your data. This is painless, as I experienced yesterday and today.

You can use super duper. If you have one, take an external usb hard disk with 
as much space as you have on your internal hard drive in your mac. Your 
external disk can of course be larger, but you will need at most the size of 
your mac drive, if you have it filled up. Super duper can create a backup of 
your entire system, all apps, system files, preferences and all that. Even the 
unregistered version of super duper does it without restriction and will make 
the usb backup disk bootable too. Once everything is backed up, you can restart 
your mac and boot off of the external disk.

Note: If you have no other usb disks connected other than your external backup 
hard disk, and as long as you only have 1 partition on the mac drive, you can 
boot from the usb disk by turning on your mac, and during the startup sound, 
hold down the option key for some 10 seconds or so. Release it, and you will be 
in a menu. The cursor is on macintosh hd, to boot from. Arrow left once, hit 
enter, and you will instead boot from the usb drive. It takes longer but it 
works. End of note.

When booted from the external drive, you have your entire system as usual. 
Voice over as well. Because everything was backed up, both disk utility and 
super duper are on this external drive too. So now, start disk utility and look 
at what you have in the disk table. You will see your mac hard drive and its 
macintosh hd partition, you will see your external usb disk that you are now 
working from with its partitions, and you may see something called a super 
drive. That is simply your mac's internal cd dvd drive.
Now, You want to repartition your internal mac hard drive into 2 new 
partitions: macintosh hd 20 gb smaller, and the sandbox partition being 20 gb 
in size.

Put the cursor on the mac hard drive itself. Not on macintosh hd which is the 
partition inside it. If you now look at the rest of this disk utility screen, 
you will find a number of tabs. One of them is the partition tab. Push it with 
vo space. The screen changes to show partitioning options.

This screen is self-explanatory, except for one thing. There can be a scroll 
area. First, you need to choose how many partitions you are going to have in 
the new layout. You will find a pop button for this. After you select to have 2 
partitions, a scroll area will appear. It consists of 3 items: the first 
partition, a separator and the second partition. Focus on your first partition 
inside the scrool area and stop interacting. Now, look left and right of the 
scroll area, and you will find places to give the partition its size, name, and 
file system. Then go back to the scrool area again, focus on the second 
partition which is your sandbox, and fill in the details again for this 
partition. Then hit apply, let disk utility do its thing, and then exit disk 
utility. Now you have a macintosh hd partition 20 gb smaller, and you have your 
20 gb sand box partition. Both partitions are in place but they are empty.

Now, use super duper to restore from your external drive back to macintosh hd, 
so that your system is back normal again. 

In super duper, choose your external drive in the source pop up button, choose 
macintosh hd as the destination in the second pop up button, use the backup all 
files item in the next pop up button, and let it do its thing. Now, you can 
boot as usual and nothing should be different. All data is back on your drive, 
inside macintosh hd.

Now for the sand box. Having booted normally, start super duper. Tell it to 
back up from macintosh hd, to the new 20 gb sandbox partition, using the choice 
named sandbox shared users as your backup method. Don't use smart update this 
time yet. You want to be sure that everything is backed up from macintosh hd to 
the sandbox partition.  When done, close super duper. Now you have your sandbox 
in place. Forget about it, until you want to test a new device driver or piece 
of software.

When that time has come, you will first need to boot from the new sandbox 
partition. To do that, either do it using the option key at startup, or go into 
system preferences, the item startup disk, and set it to boot from sandbox. 
This will hold for all subsequent boot ups, until you change it back.

Once booted into your sandbox, install the software or drivers and try them 
out. Reboot when you want or need to. Sandbox will automatically be the booted 
partition because you did that in system preferences. If you are satisfied with 
the new software, you will have to install it a second time, but now on to your 
real macintosh hd partition. Go to system preferences, change the startup disk 
back to macintosh hd, reboot, and install your driver or software.

Note: from time to time, it is a good idea to update your sandbox to reflect 
the state of your ever changing macintosh hd. To do this, use super duper. 
Backup from macintosh hd, to sandbox, backup all files, and use smart update to 
bring down the backup time. To turn on smart update, find the options button on 
the super duper screen, hit it and select smart update from a pop up button. 
Hit ok to close options and hit copy now. Your sand box is now up to date 
again, ready for the next unknown bit of software you would like to have a go 
at.
Lastly, repartitioning your external drive should now be a snap. If you have 
further questions let me know.
Hth,
Paul.
