I would troll around for a good data recovery question that's already been thoroughly answered and make that one the canonical example. We've answered the question more than once in the past
It gets a bit more complicated with Data Recovery as sometimes it's physical damage where other times it's accidental erasure, and the process for tape versus HD may be a little different (more you can try with tapes before shipping them off), so maybe something like the Capacity Planning question that then links to physical versus digital questions might be sensible...
