I am doing some hard drive shopping and I was wondering is there a certain way to tell if a hard drive is compatible with an xbox. I have a version 1.0 xbox and I Know it has to be lockable but is there any certain requirments. Here are some I was considering. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2765002&CatId=523 http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2943586&CatId=524 http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3306148&Sku=TSD-320M2
