Microsoft to block unlicensed memory cards

Microsoft has said that consumers will no longer be able to use unlicensed memory cards on the Xbox 360, once it introduces its new dashboard update.

Official cards from Microsoft and those carrying the Xbox Live Compatible logo will still work with the system.

"When Preview Program members start receiving the Xbox 360 system update next week, one of the changes is that unauthorised memory units will no longer work with the Xbox 360," said Xbox Live's Larry Hryb.

"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 unauthorised memory unit after the update, you will not be able to access your stored profile or saved games," detailed Hryb.

The new dashboard update will add Facebook, Twitter and Last.fm services to Xbox Live, along with news and other services.
