SR2: Data corupt on install?
 

So I'm trying to install SR2 from CD (the 2006 release, that included a re-release of SR1 in the box), and while it starts out fine to begin with, after a while it stops installing on the first disk, and announces "Data Corrupt." and stops. The disk looks fine, free of scratches and dirt. How do I fix this?

I'm running XP Home with auto-updates, so it should be the latest version of the OS.

Addendum, SR1 installed without issue, if that helps.
