I want to use the HDD from 2008 iMac with OS Lion for the first generation intel iMac 2006 which doesn't support OS Lion. 

I want to erase or initialize the HDD to reinstall OS Snow Leopard for iMac 2006.  What is the best way to do?  To erase all the data using disk utility, which format I need to specify?  Thank you for your help!
