Eu tenho um disco rígido Seagate Barracuda de 2 TB que um amigo me deu para tentar restaurar alguns dados, mas estou com problemas estranhos.
Primeiro, a unidade ainda gira quando você aplica energia. Nenhum som incomum está vindo do disco rígido. Se eu conectá-lo em uma área de trabalho do Windows, o disco rígido aparece como um dispositivo removível (mesmo que eu tenha conectado diretamente ao meu computador via SATA) que não está formatado. Não tenho certeza de por que um HDD normal seria exibido como um dispositivo removível.
A próxima coisa que notei foi quando reiniciei meu computador com apenas sua unidade conectada à minha máquina, ela não é reconhecida na BIOS por algum motivo estranho. Eu carreguei o Ubuntu Rescue em uma unidade USB e inicializei meu computador nele. Aqui estão as saídas de alguns comandos para dar uma idéia de como é o / dev, etc ...

Para falar a verdade, até agora esta distro do Ubuntu Rescue tem sido muito abaixo do esperado. Eu estava esperando que tivesse pelo menos uma GUI básica (se isso acontecer, não carregaria na minha máquina de teste que pode carregar x janelas sem problemas quando eu inicializar qualquer outra versão do Ubuntu) para que eu pudesse facilmente explorar as ferramentas disponíveis mas, em vez disso, fui forçado a instalar o lynx e navegar na internet e ler a documentação para descobrir quais ferramentas estavam incluídas na distro.
De qualquer forma, aqui estão minhas perguntas:
O que faria com que a unidade fosse exibida no Windows como uma unidade removível que não está formatada, mas a mesma unidade não parece ser reconhecida no BIOS?
Eu tenho um segundo disco rígido de 2 TB que estou preparado para usar para copiar os dados - mas alguém tem alguma sugestão para configurações de hardware no BIOS (a placa-mãe é Intel DZ68DB)?
Alguma idéia de por que um disco rígido que está sendo conectado via SATA seria mostrado como uma unidade removível?
Alguém pode sugerir algum software que eu deveria dar uma olhada @ para ajudar com esse problema? Estou muito confortável com o Linux ou o Windows, por isso as ferramentas para qualquer uma das plataformas estarão bem.
Deixe-me saber se você precisa que eu poste a saída de quaisquer outros comandos do Linux na máquina que estou usando para tentar restaurar os dados.
Como último recurso, o segundo HDD de 2TB é o mesmo modelo / modelo exato de HDD. Alguém tem sorte de trocar o circuito da unidade entre duas das mesmas unidades exatas? Tenho formação em Engenharia Elétrica, mas tenho que admitir que nunca tirei o PCB de uma unidade e troquei-o por outro. Parece que pode ser possível, mas prefiro não recorrer a medidas tão extremas.
A razão pela qual eu estou envolvido nessa situação é que eu acho que há fotos neste HDD de alguns membros falecidos da família e esta é a única cópia que ele tem desses dados. Eu já o li o ato de revolta sobre fazer backups offsite regulares, mas isso não faz muito para ajudar a resolver a situação na mão.
Qualquer ajuda seria ótima - obrigado!
Algumas portas SATA na placa-mãe podem ser configuradas para uso "ESATA", para hotplugging. Isso tornaria a unidade vista como removível.
Portanto, verifique as configurações da BIOS para as portas SATA (você provavelmente precisará obter o manual da sua motherboard), que descreve quais portas podem ser configuradas para hotplugging.
