The hard disk was replaced, the programs and data restored, and it doesn't look like we lost a single bit or byte. All things considered, it went surprisingly well.
However, fixing the hard disk problems didn't fix the DNS problems which first prompted my investigation yesterday. Those remain unresolved, and it's quite possible I'll have to take the server and forums off-line later to run further tests. You can probably figure that "later" is going to be at least ten hours from now, though, because that's about how long I expect to sleep.
