Oh... well in that case...
Since you are going to just get another drive, then have at it. However, I can't think of a utuility off the top of my head that would do the job without allowing itself to get mired in read-errors. You may very well have to go for a reinstall, and that may be the preferred course of action, especially if you have a cache of your preferred programs' install apps. This way you have a clean install with everything you want and no remnants of what was left behind.
And don't forget to back-up/export your settings - especially those bookmarks! They can be a pain to rebuild.
