RECOVERY (default) and SPEED are mutually exclusive.
Recovery preformats the control areas during the initial
dataset load, if the job fails, you can restart but you must
have a recovery routine already written to restart the job.
SPEED does not preformat the CAs. It is recommended that you
specify SPEED to speed up your initial data load.
