Well, bad power can do this... ideally you'd want UPSs on server, workstations and switches.

If you can get exclusive use of the database, you can issue VALIDATE DATABASE RECOVER, which will rebuild the structural .DCX index file. You can do this even if the .DCX is deleted i.e.

ERASE MyDB.DCX
OPEN DATABASE MyDB EXCLUSIVE
VALIDATE DATABASE RECOVER

If the database container never changes, one trick you could try would be to mark the .DBC/.DCT/.DCX files as read-only.
