# Verify the startup volume

OnyX allows you to verify the structure of System Files on the startup volume and the option of running this verification upon launching OnyX. Before running this verification, OnyX will quit all open applications (some tasks can inflluence the results of this check).
Important: During the verification process, the Finder may become slow or unresponsive. The spinning pinwheel may show up, or your computer may appear to be unresponsive. This is normal, so please wait!
Warning: This verification option is only possible if the hard disk is Journaled.

Run OnyX and type your administrator password.

Click the Verify icon then choose the Structure of volume tab.

Click the Check button to immediately verify the startup volume.

By default, OnyX asks you if you want to check the structure of the startup volume at OnyX launch. You can choose to automatically check it or to do nothing by selecting the corresponding option in the Advanced tab of the OnyX Preferences panel.
