I have a MacBook which is a few years old now. When I run the "Verify disk" command from within Disk Utility, I get a message:

Volume header needs minor repair
The volume Mac OS X was found corrupt and needs to be repaired.
Error: This disk needs to be repaired.  Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.

When I boot using the OS X installation disk which came with laptop and use Disk Utility there to repair the volume, it reports:

The volume Mac OS X appears to be OK.
No repairs were necessary.

When I reboot back into the normal OS and run Disk Utility again it still reports the previous error.

This laptop came with OS X 10.4.6, but has since been upgraded to OS X 10.6.x. I presume that I'm unable to use the installation disc to repair the volume because it is too old for the upgraded operating system and filesystem.

Without owning a physical install disc for OS X 10.6, how can I repair the volume?

(Note: I was able to borrow an install disc for OS X 10.6, but unfortunately this was from a 64-bit Mac and wouldn't boot, my MacBook is 32-bit only.)

In order to upgrade to 10.6, you would have had a retail Snow Leopard install disk. That install disk will be able to boot on your computer.

If you do not have the install disk, you may need to purchase a new one or purchase a separate drive repair tool like Drive Genius.

Interesting... I had a look but couldn't find an install disc in my cupboard. I'd assumed OS X 10.6 might have been an internet upgrade that didn't come on physical media (I honestly don't remember the upgrade process). Perhaps I should look harder for my disc.. – pauldoo Oct 19 '12 at 17:55
    
Nope, first internet upgrade was Lion. – Alan Shutko Oct 19 '12 at 18:02
    
After finding my 10.6 install disc this did the trick. Excellent. :) – pauldoo Oct 19 '12 at 19:26
