Macintosh HD Not Getting Verified In DIsk Utility

[W4133D]

As the title says, I go to Disk Utility and I click verify on Mac HD and I get an error saying Keys out of order.
Someone please help.

You have to insert the grey cds so as to repair your HD

Will that delete all the files on my drive ?

Nope!

Edit:Unless you do a clean install
