RE: checking for block corruption

This only works in 11g.  The original poster stated that the database is a 
10g database.

RMAN can do a validation of the datafile-  You don't need a backup in 
advance to do this.

In RMAN -   validate datafile X;  where X is the datafile number.  Then 
check v$block_corruption for additional results.

You can also use Database Verify (DBV) utility.  DBV is a standalone 
program, so the db does not need to be running to use dbv.
For raw devices I have never used DBV- may or may not work :)
