Parece que estou tendo erros ocasionais de E / S de SSD (Patriot Blaze) embora todos os testes mostrem que o disco é saudável, limpo e operacional, com apenas 7 meses de idade.
UPDATE : Uma terceira instância de congelamento de disco foi totalmente congelada com a luz CAPSLOCK piscando. Hard desligar e reiniciar resolve o problema.
Inicializando 16.04 LTS às vezes falha, exibindo o erro "não há dispositivo inicializável" , e reinicia ou desliga / liga resolve o problema, e inicializo o Ubuntu bem.
Em outras ocasiões, ao usar o Ubuntu, o sistema pára de funcionar, enquanto eu posso mover o mouse, mas não consigo abrir nada. Eu também recebo o seguinte erro :
JavaScript error in the main process
Error: EIO: i/o error, read
at Error (native)
at Object.fs.readSync (fs.js:651:19)
at process.binding.internalModuleReadFile

at Function.Module._load (module.js:290:25)
at Module.require (module.js:357:17)
at require (internal/module.js:16:19)
Por exemplo, a última vez que isso aconteceu eu reiniciei e recebi o erro nfrarm que dizia que eu deveria executar fsck do meu SSD, então eu fiz e consertei alguns erros, e agora funciona bem . Mas, novamente, isso vai acontecer novamente.
Agora, a análise de autoteste (> Discos) não revela problemas (DISK OK). É um SSD de 128 GB em operação por 7 meses, e o Lenovo z51-70 tem 8 meses de idade também.
O teste Smartmontools não revela problemas, smartctl -t short -a / dev / sda:

Por que isso de repente? O SSD pode falhar sem o relatório de testes?
Felicidades.
