With 10.4.9, I thought I could repair the disk right from Disk Utility
instead of using the installation CD. Now the repair button is grayed
out and I can only verify it. Has it always been so and I'm just senile?

Most grateful.

You may still be senile, but no, you can't repair a boot volume.

You can test it but must be booted from install media (or other, such as
DiskWarrior, TechTool, etc.), external bootable drive (such as a backup - you
*do* have a backup?), or another Mac.

How do you boot from "another Mac"?

I think he means that you would use Firewire Target Disk mode.

If you connect two Macs together with a Firewire cable, shut them both down, then hold down T at startup on one of them to boot into Firewire Target Disk mode, you can boot the other Mac and Mac OS X will mount the other Mac's startup drive on the desktop.
