Reformatting External HD to FAT32

I bought a 300gb Maxtor external hard drive to put all my photos and videos on, but it is formatted to work with Windows but not Mac (NTFS format I think, not quite sure). I am getting my 20"iMac in the mail tomorrow, so I want to put all the stuff on the HD onto my PC, format it to FAT32, and put everything back on. Could someone give me a step-by-step on how to do this? I have an iBook if it matters, in case I need to plug it into a Mac to format it. Thanks for the help, it is greatly appreciated!

I think I got it, its formatting right now. I just had to partition it into 133 gb sections. Someone delete this thread.

How did you end up formatting it? I asked in another thread but no one answered...
