Подскажите в чем может быть дело это hdd накрывается или контроллер на матери глючит? Диск стоит от внешнего seagate expansion desk, изъял его из кейса, дабы подключить как внутренний hdd.

Сдох. В помойку.

Да, диску кирдык.

Если дохлые сектора где-то в одном месте сосредоточены (имеют близке номера) то можно конечно переразметить отсавив сбойную область неразмеченной. Но такое редко случается, а главное - это довольно трудно узнать т.к. сектора которые были перенесены - они не будут в отчете о сбойных (они на другие места переехали).

Но 888 pending - это уже совсем плохо... лучше все-таки покупать новый винт и сливать полезные данные с этого дохляка.
