Olá a todos,

Estou enfrentando um problema que não consigo resolver. Tem um notebook Infoway Note W7410 que tem um HD SATA que começou a apresentar desempenho muito devagar durante leitura/escrita com Windows e com Linux. Se vocês poderem ajudar porque eu já tentei vário comandos com o hdparm e com o smartctl além de tentar alterar a tecnologia SATA na BIOS entre AHCI e IDE mas não consegui resolver.

que eu saiba, sdparm é melhor para os HDDs SATA, mas se o desempenho baixou tanto em windows como em Linux, isso me indica que seu HHD tem problemas.

Eu diria que ele está indo pro sa...

Parecem problemas de hardware e não do SO.

o que sugiro,e correr um um recuperador de HDD. o melhor quer conheço é o hdd regenerator.

ele roda com qualquer SO, em CD de boot e qualquer sistema de arquivos e não apaga os dados.
as versões para windows são pagas, mas a versão em linha de comando é gratuita e pode ser encontrada dentro de um CD de recuperação que pode ser baixado da Internet, chamado Hiren's utilities.

eu usei em um SATA velho e recuperou, mas demora muito e não pode ser interrompido. no Meu Atlhon duplo núcleo 64 bits, meu HDD de 500, levou: 3 DIAS E MEIO, mas funciona.

Nossa senhora, 3 dias e meio, credo.

Cara valeu por responder a minha pergunta.
Não sabia que existia um sdparm, vou tentar utiliza-lo.
Eu também acho que o HD foi pro beleléu mas eu quero conseguir provar através de algum teste ou relatório que o problema realmente é no hardware apesar de a experiência já informar isto.
Quanto ao aplicativo sugerido, vou tentar utilizado para poder dar um retorno se funcionou com o HD para que o pessoal da comunidade possa usufruir da minha experiência com o aplicativo.

Novamente, valeu por responder o tópico; afinal, a essência da vida é compartilhar.
