How can the xbox media center recognize an external hardrive? - usb hardrive adapter radio shack

I have an external Hardrive with movies that I see in the situation as the Xbox, to play with them. I have a USB adapter fine and reads my 2gig USB flash drive when you can not read the disk, then add a second IDE cable from inside the Xbox, then remove the hard drive from Box and Xbox directly linked to the job?
