Summary: bad sectors


Bad sectors can be handled by flagging them in the bit map (unless the
superblock or a bitmap block are bad).  The extra space in the super
block should be used to save a list of bad zones.  There are two 
approaches:

	1) modify fsck to know about the bad block table.  Write
	   a utility to maintain the list in the super-block.
	2) write a utility that reads a list of bad blocks and
	   turns them into files on an unmounted file system.
	   This does not handle bad blocks in the inode table.
