Hi, Jerry Juan~ Very intresting task.... Well, to manage 2 sd-card at the same time: 1. patch vold in several places, to allow it manage multi-devices at same time. But, vold is just "tip of the iceberg" 2. patch/add a loooot of component on framework level. As there are located the main concept of sd-card usage in Android OS. 3. and as last, you have to read the next thread. ;) http://groups.google.com/group/android-developers/browse_thread/thread/70566347c0953488/5466def3ced9bfde?show_docid=5466def3ced9bfde
