Minha unidade externa não pode ser acessada. Parece que a montagem automática trava. Quando clico em "Montar", recebo "não é possível acessar o volume - uma operação já está pendente". Quando tento remover a unidade, recebo: "Não é possível parar o WCD - Erro ao abrir/dev/sdb para fsync: dispositivo ou recurso ocupado."
fdisk -l /dev/sdb trava.
dmesg contém os seguintes avisos recentes:
task scsi_eh_6:5019 blocked for more than 120 seconds
...
task fdisk blocked for more than 120 seconds
...
task mount:5301 blocked for more than 120 seconds
...
task pool-udisksd:5059 blocked for more than 120 seconds
Etc. Toda vez que tento acessar a unidade, o processo que tenta acessá-la trava e não consegue acessá-la. Tentei executar badblocks e até ele congelou depois de vinte minutos - badblocks bloqueados por mais de 120 segundos, etc.
Não tenho certeza de que tipo de problema de hardware faz com que todos os processos que tentam se comunicar com o disco (incluindo todas as ferramentas de diagnóstico) congelem. Nenhum deles pode ser encerrado por Ctrl-C, tenho que sair do terminal. O que devo fazer?

O utilitário gnome-disks diz que o sistema de arquivos Ext4 no disco não está danificado e os testes smartctl apenas retornam "tempo limite de conexão esgotado". Então, como vai?

Isso indica que nenhum bloco defeituoso foi realocado ainda, mas que 166 blocos são suspeitos e estão causando erros de leitura bruta e erros incorrigíveis.
Você precisa verificar manualmente o seu HDD em busca de blocos defeituosos e, em seguida, deixá-lo remapear os blocos defeituosos para você.
Note: do NOT abort a bad block scan!
Note: do NOT bad block a SSD
Note: backup your important files FIRST!
Note: this will take many hours
Note: you may have a pending HDD failure
Inicialize em um Ubuntu Live DVD/USB.
Em terminal...
sudo fdisk -l# identifica todas as partições do "sistema de arquivos Linux"
Nota: se fdisktravar para você, tente identificar sua(s) partição(ões) ext4 do Ubuntu usando gparted.
sudo e2fsck -fcky /dev/sdXX# teste somente leitura
ou
sudo e2fsck -fccky /dev/sdXX# teste não destrutivo de leitura/gravação(recomendado)
O -k é importante porque salva a tabela de blocos defeituosos anterior e adiciona novos blocos defeituosos a essa tabela. Sem -k, você perde todas as informações anteriores do bloco inválido.
O parâmetro -fccky...
-f Force checking even if the file system seems clean.
-c This option causes e2fsck to use badblocks(8) program to do a
read-only scan of the device in order to find any bad blocks.
If any bad blocks are found, they are added to the bad block
inode to prevent them from being allocated to a file or direc‐
tory. If this option is specified twice, then the bad block
scan will be done using a non-destructive read-write test.
-k When combined with the -c option, any existing bad blocks in the
bad blocks list are preserved, and any new bad blocks found by
running badblocks(8) will be added to the existing bad blocks
list.
-y Assume an answer of `yes' to all questions; allows e2fsck to be
used non-interactively. This option may not be specified at the
same time as the -n or -p options.
