Speaking today, Larry 'Major Nelson' Hryb has said that a new dashboard update due in November will render unofficial storage devices inoperable on the console.

Part of the update is specifically aimed at putting a stop to what Nelson describes as 'unauthorised' storage.

"One of the changes is that unauthorized Memory Units will no longer work with the 360," the big cheese explains.

"If you've moved your profile or saved games onto one to 'back it up,' you'd better move it back onto an authorized Xbox 360 storage device prior to taking the update. If you continue to use an unauthorized Memory Unit after the update, you will not be able to access your stored profile or saved games."

More on the forthcoming enhancements soon.
