          USE -b OPTION TO FSCK TO SPECIFY LOCATION OF AN ALTERNATE

    We tried using the superblock 32 with similar results. We have an old
backup but we have made a lot of work since then, and we would like to recover
as many files as possible. Does anybody have any magic recipe ??

If you are on a SUN 4.1.x you could run newfs -N /dev/rrz2g, this will print out all
file system parameters without trying to create a new file system. You then can use
these different block numbers. It can be a long process if there are many, but you may
find one that works. EXAMPLE:
        1). newfs -N /dev/rrz2g
                produces block numbers where the superblock has made copies
        2). fsck -b <block number> /dev/rrz2g

good luck!!
