>Is there a free program of class that can fix most of problems with databases an tables (corrupted indexes,bad tables, memos, etc)?

Stonefield Database Toolkit (SDT) isn't free (I don't know of any program that will do what you want that is), but it will repair corrupted table and memo header, recreate corrupted indexes, and even create or update table structures automatically at remote sites. More information and a demo version are available at www.stonefield.com/sdt.html.
