I don't know when, or why, but I just plugged in my phone and my SDCard has been erased. I had about 12GB of music, movies, pics. Some are backed up, but I don't know about all of it, hard to know what you lost when you can't see what was there. I pulled out the SDCard, did a scan on it hoping something would turn up. nada. Just a word of caution, apparently SDCards are can be fairly volatile, so be sure to back up often.
