I did write a set of scripts that exclude e.g. certain files by
modifying the log file. I'll publish them and the accompanying
documentation (so far a little over 50 pages) as soon as it's finished.
Unfortunately I got set back a little by another data rescue case.

I like that idea. However, the question becomes what to do in the case
of bad sectors, i.e. if you want your hard drive to churn away at the
high-priority sectors (e.g. file system structures) possibly without
ever getting to the lower-priority actual data.
