Well Im doing a project to make a toy into a exteranl hard drive. I wanted something bigger than the average hard drive that wasn't to expensive. I been searching around and found this: http://www.overstock.com/Electronics/Toshiba-Ultra-ATA-100-Internal-Hard-Drive/2930201/product.html I want it to have the same hook up as the WD externals have. where can I find the other part where it hooks up, sorry I don't know the proper name for it. Hope someone can help me!
