Hi!
Bob offers a lot of good advises. Some other comments:
MySQL will not loose data if you take it down properly! In any case,
if isamchk doesn't find any errors on your tables it means someone has
deleted the missing rows with an SQL statement!
Do you have an update log? If yes, you should be able to restore
things quite easily.

Monty
