I've been flashing ROMS to my old original DRIOD for the past year, but I haven't done anything yet to my Nexus. I wanted to get used to stock so I would know what I would like to see in a new ROM. Well, anyway, one thing occurred to me, and I haven't seen a discussion of this specifically, so I thought I would ask. I put my new ROM, Nandroid backup, TiBU files all on the "sdcard" -- /mnt/sdcard. Which isn't a real separate physical storage medium but a FUSE file system created from /data/media. So, if I do a factory reset, isn't everything on the "sdcard" deleted? Is the factory reset that CW does something different from the factory reset that is done from the Settings -> Backup & reset? Is it now typical behavior to make a full backup of your "sdcard" before flashing? If the "sdcard" is deleted, how do you restore it while in CW? I could probably learn all this by just charging ahead and trying, but I want to know as much as possible before starting.
