If I format my SD card or replace with a new SD card, what will I lose? If I format my SD card or replace with a new SD card, what will I lose?


What Personal data
What Application data
What downloads


In short I want to find what, where and how data is stored on SD.
Go to Settings -> Applications -> Manage Applications -> SD Card to see what apps are on the SD card.  Other things that might be on it include pictures and videos.  There aren't a lot of things that default to the SD card, but it depends on your device and software.  The easiest way to find out what's there is just to look!
