If this happens you could lose many rows of a table or even multiple tables. Worse still, pointers may be pointing at the wrong rows, meaning that a future UPDATE or DELETE FROM much affect the wrong rows. In any properly working system even integrity-check (more thorough than quick-check) never fails, and neither should be necessary in anything except a rarely-used maintenance procedure. They are both diagnostic tools for faults, not part of a smoothly running system. If your quick-check reports a fault, you need to replace your hardware or investigate the problem until you've found a cause. If it doesn't, then there's no point in running it and you can save your users from having to wast their time. Simon.
