How to recover files as much as possible, if i only have 'storage/blocks' ?

Hi all. i lost some file, may be hardware error, include all database、some ‘storage/fs’ , some ‘storage/commits’, some ‘storage/blocks’, and no backup. How to recover files as much as possible ?

i execute 'seaf-fsck.sh -r ', only recover some folder , but no any files.
