    Have you tried what it suggested you? Copy the (spare) superblock 8193 with e2fsck

    e2fsck -b 8193 /dev/sda1

    What is weird is that you say you unmounted the disk. I am surprised this disk could be mounted in the first place if the first superblock is damaged.

    breathing is not safe will all the pesticide in the air...

    I do not understand how your /dev/sda1 can be mounted with a bad first superblock.

    Please confirm that /dev/sda1 is really mounted.

    mount | grep sda1

    /dev/sda1 on /media/WD1TB type ext3 (rw)

    not just pesticides, breathing oxygen is causing olding biological system(creating free radicals O, OH, that destroy mitochondria - later cell, problems with reparation of DNA that leads to mutations in genome -that leads to - the apoptosis of damaged cell)

    So can you access what is on the partition?

    If yes, it is time to make backup of your data and then try the e2fsck -b...

    indeed the move I was to propose you.

    doesn't solve the problem but is less annoying.

    Anyway back up your data and:
    e2fsck -b 8193 /dev/sda1

    if it is stil not working then reformat will be the only solution I can suggest you (it is maybe not the only one that exists, but the only one I can think of with my limited knowledge)
