Fall 09 Dashboard update will also render "unauthorized" memory units useless

[StarPilot]

Nothing too big for those who are using MS HDDs or memory units, but those who are using something else for 360 storage, you might want to move your data to the (overpriced) official storage devices.

Don't worry, folks -- Microsoft knows you really hate those subversive little devils making third-party Memory Units, what with their 2GB and 4GB offerings for the Xbox 360. In an effort to stamp out these Doris Dogooders from your Xbox Live Experienceâ„¢, Microsoft's Major Nelson announced on his blog yesterday that "When Preview Program members start receiving the Xbox 360 system update next week, one of the changes is that unauthorized Memory Units will no longer work."

In plain English, this means that any third-party Memory Unit you might have been using will be rendered useless. Mr. Hryb suggests moving any saves on said devices get moved to an authorized one, unless losing access to "stored profile or saves games" simply ain't no thang for you.

Granted there is hardly any market penetration for unauthorized data storage for the 360, but it's something to know about ahead of time at the very least.
