Re: How to remove corrupted blocks from datafile.

I'm sure you'll receive lots of good advice, but here goes some more (maybe not good?): The Velpuri Backup and Recovery book has some very good descriptions of exactly how to cope with this. There are a number of packages you can use to flag the blocks as bad and effectively stop them from being used, or recover them, whichever the case may be. Of course, it's always a good idea to check the actual hardware first!
