So I've got a customer where I work (yes I sell phones) who has a fascinate and every couple days or so everything on his SD card disappears from the apps. Pictures are invisible to the gallery, music to the music player. It's still there under my files, and I tinkered with SD card and booting in and out and what not, but I couldn't get anything to come up. I pulled his SD card, and put mine in and everything on there showed fine. I sent him home to Format his SD card and then replace the contents to see if this helps, but honestly I'm 50/50 on whether this will help. Anyone who has experienced this and has a fix would be much appreciated.
