OK, I took an hour or two to read through everything in this forum, and am still a little sketchy with all this information. I didn't want to interrupt this forum with noob talk, but I would really like all this clarified. Here's what I have gathered is possible to this point
1. Ripping an exact copy of the current Xbox HD onto an SATA 2.5" HD at 20GB, regardless of whether or not your HD is bigger, and replacing the old HD. This hard drive can utilize the normal Xbox 360 HD functions (music, pictures, gamesaves). This is essentially pointless to do at this point, as it does nothing that the standard HD cant do.
2. You can hook up any 2.5" HD to the USB port and play music and pictures. This too is rather pointless, as you really dont need that much space if you cant put videos on it.
If I'm wrong in any of this, someone please correct me. What I would like to know is if there is ANY possible way to at this point to load videos onto a HD from your PC and play them on the 360. The other major thing I would really like clarified is whether you can get the Xbox 360 to recognize a hard drive plugged into the USB port in addition to the standard one plugged into the SATA port.
Thanks in advance for any help, and once again I'm sorry to nooblify this forum, but I didn't know where else to look for these answers.
