Myself i would not send in a limited edition Xbox in for repairs as you will not get the same one back!!!!!
Incorrect - they have to send you the model that you sent.
So if I sent in a 360 with HDMI port I am going to get one back with a HDMI port.
Send back a black elite, going to get back a black elite.
Same with limited editions, MW3 will get a MW3 console back etc..
If you have a Signed console - you will not get that back - but the is more the exception.
Tonia - do you have a 20gb drive that you are trying to transfer from?
These small drives seems to have a problem transferring with the cable at times.. There is no fix that I know of other then to move everything that can not be downloaded from your History via USB.
