Hi 
 As stated in the infocenter: " Deleting a record does not actually delete the record data and clear the used flash space, but it invalidates the record.....Instead of deleting records right away, FDS relies on garbage collection to reclaim flash space used by records that have been invalidated." 
 Which means that your record will not be deleted if you have not invalidated it by calling the function fds_record_delete (&descriptor) first. More information regarding the FDS library can be found here 
 Moreover the garbage collection will delete every record that has been invalidated once it is called.
