Sadly, you have not fixed any of the bad blocks by deleting the files.  
The bad blocks will only be replaced when they are written to.  Now 
that the files are deleted, you will need to write to all the free 
space of the drive to write to the defective blocks.  This should do 
the trick (as root, or from the Rescue CD):

    # cp /dev/zero junk ; rm junk

I don't expect it to find any defective files, as you already deleted 
them.
