Need help formatting to fat32!

First, I would like to thank you for any help you can give me. I dont know much of anything about computers and im trying to format a 40gb hitachi hard disk via USB cable using VISTA for use in my PS3(must be FAT32). When I click START>COMPUTER, I don't see the hard disk. If I RIGHT CLICK COMPUTER>MANAGE>DEVICE MANAGER>DISK DRIVES I see the hard drive. Whats going on here? Should'nt I see it by clicking Computer? Aside from that, I've seen online that I wont be able to format 40gb in FAT32, although it seems there are ways around it. Can somebody please help me through this, it's driving me nuts.
