If you open the Terminal (located in Applications/Utilities) and run ls /Volumes , does the name of the hard drive show up in the listing? What happens if you go into the Finder, choose Go->Go to Folder... and type in "/Volumes" as the destination folder?

I don't know why the drive isn't mounting on the desktop, but a temporary solution that I can think of is to go back to the Finder, and do the Go->Go To Folder... thing again. Select the hard drive, and choose File->Make Alias. It will create a shortcut to the hard drive which you can drag onto your desktop for quick access.

Seems like your hard disk has crashed. Try using disk utility and repair your external hard disk. I also want you to test out the external hard disk on other macbooks and see whether it can be detected. Before using lion, when using snow leopard does this problem occur or this occur when changing from Snow Leopard OS to Lion OS.

Your hard disk has crash, you need to get a new hard disk. Try sending it to a local repair shop and have some expert to closely look at it.
Do this steps
1) On your mac and insert the Mac OSX Installation Disk into your mac mini
2) Restart your mac and hold down the option key as it boot up again
3) Select the disk and choose your language.
4) When you enter, remember do not reinstall snow leopard at the top of the screen there will be a utilites bar something like that.
5) Go and search for disk utility and use it to repair your hard disk. After you are done, restart your mac but this time boot up from the internal hard disk.
See whether that works, if that fails most likely you need to get a new hard disk for your mac. Send your mac to an authorized apple store and get the technician there to help you fix.

I had this issue once and it turned out to be a disk failure. I was able to access the disk after several attempts at booting.
First try booting the setup CD/DVD and run a disk repair and repair permissions. With any luck this will fix the issue. Otherwise, use the system disk to boot. Access the drive from terminal and transferred as many files as you can to an external. Then replace the drive and make a clean install.
Probable not the solution you wanted to hear.
