executando testdisk eu posso realmente ver todos os meus arquivos em /dev/sda1 !
Eu queria instalar o Windows ao lado da instalação da minha Debian para poder jogar alguns jogos. Para fazer isso, eu tive que inicializar um DVD do Ubuntu Live 12.1 e usar o GParted (eu estava redimensionando minha partição principal que tinha tudo).
O redimensionamento foi concluído com sucesso. Eu então tentei reiniciar em meu Debian para fazer backup dos meus dados, o que eu tinha esquecido de fazer antes, infelizmente.
O GRUB carrega muito bem, mas o sistema não consegue inicializar corretamente! Chega a um ponto em que ele tenta configurar um "ramdisk", ou algo parecido; então é apenas um prompt e pronto.
Agora eu iniciei o Ubuntu novamente, para executar uma verificação na minha partição encolhida. Essencialmente, está quebrado, mas não consigo entender a mensagem de erro.
Isso é o que o GParted relatou:
GParted 0.12.1 --enable-libparted-dmraid

Esta é a saída de dmesg | tail :

Como posso consertar minha partição? Conseguirei recuperar meus dados?
Aqui estão alguns comandos adicionais que eu executei:

A entrada da tabela de partição diz "msdos" - isto é suposto ser assim?
