It is highly recommended that you enable drive calibration and qualification if you are using STA media validation. However, you can disable the feature at anytime.

1. You must have Administrator privileges.
2. In the left navigation, expand Setup & Administration, select Media Validation.
3. In the "Use Media From the Following Manual Logical Group for Calibration" drop-down menu, select None (Opt out of calibration; not recommended).
   
4. Verify your selection, and click Save.
5. Review and click Yes to confirm that want to disable calibration and qualification.
6. STA finishes any in-progress calibration or qualification activities, but does not begin any new calibration or qualification operations.
