Query: What's really "Missing" is some basic information

Fortunately I had the "Windows XP Annoyances" manual to thoroughly explain how to use Windows XP's Chkdsk utility. "Chkdsk", or any spelling of it, does not appear in "The Missing Manual" or index as far as I know, but it does in "Windows XP Annoyances". Something as basic and important as "Chkdsk" should not be missing. I wonder how many other entries are non-existent? Having read both manuals, I prefer "Windows XP Annoyances". Pogue's content reads like a rehashed Microsoft Windows XP "Help" tutorial. There's more substance in the other manual.
