Cannot see 2nd hard drive in nautilus

I am a fed up user of Windows and am giving Ubuntu a try. I have really been liking Ubuntu and have been able to solve all problems but this one by scouring the web and sifting through books. I installed a second hard drive and formatted it in Ubuntu in FAT 32 so I could share files on it with Windows computers. Orginally I could see the second hard drive in Nautilus and manually mount it from there. However, I did not want to manually mount the hard drive every time I start the computer so I used gpedit to automatically mount the hard drive to '/home/jimmy/Desktop/disk'. It works, and I can see the folder 'disk' on the Desktop but now the hard drive does not show up in Nautilus. I used the partition editor and it shows the hard drive as mounted to both 'home/jimmy/Desktop' and to '/media/disk'. So my question is; how do I get the second hard drive to show back up in Nautilus? Any help will be greatly appreciated. Thanks.
