Hard Disk Icon Image Missing


Ok, I'm not a noob to macs, but this boggles my mind. I replaced my desktops hard disk icon with a new one. I didn't like it and wanted to change back but, I can't find the original hard disk icon. I searched my hard disk for "hard disk" and "icons" but nothing came up. Then I searched the net for the original icon image, as well as apple's website and only come up with thrid party icon sites. Can someone tell me how I can get my original icon back? This should be such a simple task...lol.
Click on your hard drive and do a "Get Info" by pressing Command-i. Highlight the hard drive icon in the "Get Info" window by clicking on it, then press delete. The custom hard drive icon should disappear, revealing the original icon.
