Well there's two hard drives the one that is built in or the one that you buy. The one that you can buy which clips onto the xbox if you know what I mean. But if your on about the built in one then yes you need it.
Only if you have a hard drive. Otherwise they will not work without a hard drive.
No it does not.
yes. buy you will need a hard drive in order to be able to play them. usb memory wont work.
No it wont the Xbox 360 is the only Custum System that you can transfer the hard drive but it is not possible to switch it for a Xbox one.
If you have a hard drive. If you do not have a hard drive in your 360 it will not workAll Xbox games will work on a 360 that has a hard drive (elite and pro come with hard drive). Arcade version owners need to buy a hard drive first
how does the hard drive actually work on the Xbox 360 console?
Yes it will work fine.
AN XBOX 360 has 2 front USB ports, and 1 back USB port, an XBOX 360 hard drive will work for sure. A USB flash drive will work on the xbox 360 after you get the Spring 2010 Dashboard update
