This is a big problem with ext2 in my opinion - I've trashed filesystems on my SCSI drive several times while running with an IDE drive (probably stack overwrites/cruddy ide controller). In 99% of cases I believe the group descriptors are useless on disk - a piece of information that can be corrupted, yet e2fsck doesn't give an option to 'fix' it. What approach can we take to fix this?
Sure it does. What version of e2fsck are you running? Modern ones explicitly print out a message saying you can use the backup block descriptors by using the command "e2fsck -b 8193".
