[9fans] Recovering a venti from disk failure

["Anthony Sorace" <anothy@gmail.com>]

I had a disk fail a few days ago, after a power outage here. Various
spots in the fossil partition generate IO errors. The Venti arenas
seem intact. I've bought a new (and larger) drive, and have done a
basic Plan 9 install onto that, and moved the old disk from sdC0 to
sdD0. I'd like to recover the data from my old venti. It looks like
the process looks like this:

1) Boot off new disk.
2) Recover last score from old fossil w/ fossil/last (this works).
3) Start a venti running off old disk (will require editing venti/conf?)
4) venti/copy old-venti new-venti score-from-setp-2
5) Reboot off some other medium.
6) Reformat new fossil from new venti using score from step 2.
7) Reboot off new fossil+venti.

Does that sound like an accurate script? Can anyone who's done this
confirm? By chance an easier way?
