Just use RMAN to backup your databases. It will warn you about corruptions.

Pui Ho,

   The only way you can be 'proactive' concerning corruption is to have a
sound backup strategy - if you really feel nervous about your hardware,
first change it, and then use archive logging and the rest; export is a bad
solution, because it will be long to restore. By definition, a corruption
doesn't give any warning (it's even worth than earthquakes). If you want to
be very reactive, set something to regularly scan your alert.log file.
