>From normal usage, InnoDB is sure better, i.e.

quote from MySQL:
===============
The outstanding feature of InnoDB tables is also automatic crash
recovery - in case MySQL shutdown was unclean InnoDB tables will still
recover to the consistent state, you will not have to check or repair
them.
===============

But they are talking normal/common usage, how about in the Worst Case
Scenarios?

I heard that in some rare case, if InnoDB table was corrupted, there
are no method to repair them, is that true?

So how about MyISAM vs InnoDB, in Worst Case Scenarios?
