Either the seller does not know how to shell out a proper error report....or this is exactly what he's experienced.
"Not 100% sure i thinj its e74, has to do with hard drive"
Is the exact message he gave me when I asked what sort of error it is.....

......I've already checked the error data base and the highest it goes is 21....

....
Thanks Bomb Bloke for the info but I've already checked the error codes list when the seller first mentioned that he gets an error, but thanks for trying to help.
EDIT:
http://farm3.static....pg?v=1205727168Whaaaa....googled "xbox errors" so I could explain visually where the error code is located and..I found this...if the seller says e 74.....the picture shows e 79.....what?!? why are these not in the Xbox Error Codes List?....further inquiry into the pic reveals that its from a 360.....did the xbox's made from Taiwan have different error relaying methods?
