>>>Do yourself a favour and REQUIRE that your user have UPSes. In our contracts we require the use of one UPS per PC, or we charge them for the repair of the tables. First time 100$, second time 200$, third time 400$, fourth time 800$ and so on. And we also tell our users that we can never guarantee that all data will be recoverable. After a few bills the users buy a UPS....!

Of course, I agree with you.
But this particular user makes backups regularly, and it has printed data so if anything goes wrong with table, user can easily restore database and insert missing data.
