Strange Linking Data in Webmaster Tools

[JSOC]

I run a site that was a Wordpress blog with Edirectory software for a directory on the back end. I've scrapped the Edirectory and built the entire site on Wordpress. After the site change I'm seeing about 700 404 Not Found crawling errors, which appear to be old Edirectory pages that no longer exist. My understanding is that they'll cycle out eventually.

What troubles me is the linking data I'm seeing. In the "Links to My Site" area of Webmaster tools, I'm seeing 4,430 links to the "About" page, another 2,900 to an obscure deleted directory listing page and only 2,050 to the home page.

I show 1,700 links to a terms and conditions pdf and other strange data. To summarize, I'm showing huge numbers of links to obscure pages.

Any help would be greatly appreciated.

Yes it can, what technology did you build your site with, I am a .Net developer I cam instuct you if it is .Net, someone else can do so if it is not .Net

Thanks Alan,

There are over 700 crawling errors, can a 301 re-direct be performed globally or does each 404 error need a 301 implemented one by one?

not sure why the links to the about page more then home page, but i would 301 redirect all my 404s to the home page, or better still redirect them to relevant pages.
