Access removable SD Card on TC8000

Hi.

I'm trying to write files on a removable SD Card on a TC8000 w/ KitKat.  The folder is getting created, but the files are still stored on the Internal-External partition.  I have tried many different access methods and this one is closest, but still does not work.  Here is my current code:

File sdCardDirectory = getExternalFilesDir("/storage/sdcard1");

File f = new File(sdCardDirectory, "test7.txt");

This creates a /storage/sdcard1 directory on the external card, but test7.txt is created on the internal sd card.

Can someone point me in the right direction?

Thanks.
