What is CHECK TABLE doing with InnoDB tables?

Recently we had a case where a customer got some corrupted blocks in his InnoDB tables. His largest tables where quite big, about 30 to 100 Gbyte. Why he got this corrupted blocks we did not find out yet (disk broken?).

When you have corrupted blocks in InnoDB, it is mandatory to get rid of them again. Otherwise your database can crash suddenly.
