The ext2/3 file system seems to be able to bypass bad blocks only in 
'normal' places, not in superblocks or group descriptors.  I have an old 
'80Gb' drive with 5G of bad blocks on it I am able to use successfully 
only by creating an unused partition to shift the superblock into a good 
block, and formatting the remaining 70Gb with 'mke2fs -c -c ...' (of 
course I don't rely on it; it's in a USB enclosure I use for large 
off-net file transfers).
