Consultas Involuntárias ao HD

[bnd]

Bom dia Pessoal !

tenho notado que meu hd é "consultado" em periodos de 20segundos mesmo q o computador esteja em idle... sem nenhum programa rodando e nenhum processo ou serviço q esteja consumindo memoria ou processador

reparei q isto acontece em qualquer plataforma windows inclusive ja formatei etc

fico na duvida se isto acontece recentemente ou se sempre aconteceu, meu pc é um notebook asus core2duo 2ghz hd ST9250827AS ATA.

ja cortei varios servicos do windows e processos, ate configurei p/ desligar o hd quando estiver em idle mas a consulta permanece

o que me incomoda é q quando acontece estas consultas o hd faz um pequeno barulho, nao chega a ser alto mas me incomoda

grato desde ja

up... segue mais informações do hd
