Hello Niall and Josef,
Thanks for your great help.
Finally I get all data on the disk back after the struggle on the
weekend :) I run the program you sent me, but I got nothing from it.
I guess the reason as follows:
(1) The program fetches each chunks of 16 blocks from the disk and
check if they are superblocks.
(2) My disk is sliced into 3 parts. The fist one is for MS-DOS (FAT
format), and the rest of them are FFS. It's highly possible that the
offset block of the beginning of FFS slice is not a multiple of 16.
(3) So I did:
# for i in 0 1 2 3 ... 15; do
# ./findsb /dev/wd2 $[ (estimated end of block for FAT slice)*512 + $i*512 ]
# done
After I got the info from the superblocks, getting back data was easy.
Again, thanks much for your great help. You saved a lot of my time to
reconstruct the data from scratch.
Sincerely yours,
