Diana, because you overwrote the LVM metadata on the 'fragged' disk, you need to run pvcreate on it before vgcfgrestore. Depending on which version of the LVM tools you are running, you might have a physical volume uuid flaw preventing vgscan from finding your volume group too :-( If you still have problems after that, please send the error output of "vgscan -d" to me directly (mge@sistina.com) for further help.
