I think /sdcard is the "external" storage root: Environment.getExternalStorageDirectory().
This memory can be unmounted but it can't be removed (without a screwdriver). The "removable" sdcard is /sdcard/sd. On the Samsung Vibrant (TMO) this 2GB micro is where the Avatar movie is stored and not much else. Photos may be stored at either /sdcard/DCIM/Photos or /sdcard/sd/DCIM/ Photos depending on the user's setting.
