[X4U] Can't verify disk from boot volume.

[Robert A. (Bob) Hall]

I can't Verify my boot Volume using Disk Utility while on the boot 
volume. The Verify button remains grayed out. This remains even after 
I have repaired the boot Volume with both Disk Warrior and Disk 
Utility on my external FireWire and the appear ok after the repair. 
My OS is version 10.4.11.

Can anyone tell me what the problem might be.

Thanks,
Bob
