For each disk that you're repairing, start by selecting the last volume on that disk, then click the First Aid button or tab.

After Disk Utility is done checking the volume, select the next item above it in the sidebar, then run First Aid again. Keep moving up the list, running First Aid for each volume on the disk, then each container on the disk, then finally the disk itself.
