No experience with Dreamweaver but FrontPage and Notepad++ have mass find and replace functions. If Google is showing they are 404, it sounds like the links they DID have are no longer valid and may never have been. Can you visit any of those links and see a real content page? It almost sounds like you need to decern between the actual 404 for never-existed pages (404) and those you deleted (410).
@helenp - I hope you aren't having to repeat yourself - Did you mention where Google is finding the links in the "Linked from" section of GWT? Are you able to judge that your site is the cause of most or all of them?
Yes dreamweaver has find and replace also, but there are so many links...
Not sure what you mean, think you mean where the links comes from to those odd 404, well they come from my site with the same odd patterns like:
But if I dont remember bad, I renamed 2 files as 2 sites had to many links to 2 of my pages, one site had more than 3000 links to a swedish page, and this is the strange, a parked domain.....wich had ads in it, could not see my site, had more than 300 links to I think the problematic page above hacienda_nagueles_apartments_marbella.htm
I wrote the first site got no answer, cant write to a parked domain so I renamned those 2 files and told google to delete the files that had so many strange links as maybe te drop off my homepage could be due to those strange backlinks.
So maybe those pages before had as backlinks my own pages and as well that parked domain.
I know 404 does not hurt you normally, however the drop of my homepage in december, the 50.000 excluded pages since beginning of december and now that many 404 is to much to be a coincidence.
I guess the 50.000 excluded pages did the drop.
