Por que meu drive externo está no modo somente leitura?

Question

Eu tenho este disco rígido (novo, 4 meses de idade) que gravei no ext3 (meu roteador suporta ext3, não ext4) e comecei a copiar todos os meus dados de uma unidade antiga (dados de 1 TB).

Depois de um pouco (muito tempo, copiou pelo menos 65% dos dados), eu recebi um erro e mudei o sistema de arquivos para o modo somente leitura.

O que está causando o problema? Aqui está a saída do dmesg (sdd1 - / mnt / mymedia):

Devo iniciar um RMA ou é apenas um bug do Ext3 ou algo assim? Observe que eu fiz uma atualização de firmware antes de começar a copiar os arquivos (a atualização do firmware foi ok de qualquer maneira).

O disco rígido é um Western Digital My Book

Os arquivos foram copiados por meio de cp -uR

    

Answer 1

Parece que foi um problema do GPT.
Basicamente, nem todos os softwares suportam GPT corretamente (eu estou no Debian Wheezy, o hdd tinha a partição ext3). Expecially, bad-blocks não encontraram corretamente os blocos ruins após o limite de 2 TB, então não é confiável para tal coisa (ele encontrou 800 GB de blocos ruins).

HD Scan funciona corretamente (no Windows, desta vez testado com uma partição ntfs), eu escrevi também o disco rígido inteiro com dados aleatórios e executei um teste de leitura, que funcionou corretamente.

Eu rodei o WD DataGuard que passou em todos os testes (e não encontrei blocos ruins), basicamente parece um HDD vivo. Eu só posso cruzar o dedo e espero que não seja um disco defeituoso em qualquer caso.

Portanto, verifique o GPT porque ele não é corretamente suportado pela maioria dos softwares (eu precisei do gparted para formatá-lo corretamente), o utilitário de disco do KDE não pode formatar unidades de 3TB como GPT (pode formatar drives de 2TB como gpt) isso: é um bug conhecido.
