Socorro! Não consigo ler o Superbloco
Estava usando meu pc (arch) como de costume com o Android Studio rodando, de repente ele foi corrompido e pediu para reiniciar o IDE, pois o sistema de arquivos se tornou somente leitura, reiniciei o pc inteiro e agora não consigo montar o sistema btrfs. Usando Linux 6.6.60-1-lts, btrfs-progs v6.11
Sou novato nisso, usei o btrfs porque ele está se tornando o novo padrão.
Como eu conserto isso, por favor me ajude! Até agora eu tentei:
liveuser@localhost-live:~$ sudo btrfs rescue super-recover /dev/sdb3
All supers are valid, no need to recover
liveuser@localhost-live:~$ sudo btrfs rescue zero-log /dev/sdb3

O disco rígido está saudável conforme smartctl. Nenhum setor realocado, e outras partições ntfs/ext4 estão funcionando bem.
Pelo menos se for possível recuperar os dados. Obrigado!
Estou devastado por ter perdido dados que foram esforços de anos. O único backup que tenho disso tem alguns meses, então muitas mudanças eu fiz depois disso. :'(
