For some Android devices, Environment.getExternalStorageDirectory() does not return the path of the SD card. In fact, there is no API support that will enumerate SD card mount points.
If you want to see what is mounted, you are left to parsing the contents of /proc/mounts. See http://stackoverflow.com/questions/7251793/android-absolute-location-of-external-sd-card for more discussion of this issue.
