Я пытаюсь выяснить, умирает ли мой жесткий диск. Я исследовал умные значения, и похоже, что так оно и есть, но он все равно читает и записывает данные очень хорошо, и никаких новых ошибок не появляется.
Раньше было значение 197 Current_Pending_Sector
8, но после обнуления диска значение вернулось к 0, а значение 196 Reallocated_Event_Count
равно 0.
Означает ли это, что проблема с самим диском отсутствует и это была временная проблема системы?
Также вызывает беспокойство 188 Command_Timeout
который имеет значение 1, это определяется как:
Количество прерванных операций из-за тайм-аута жесткого диска. Обычно это значение атрибута должно быть равно нулю, и если значение намного выше нуля, то, скорее всего, возникнут серьезные проблемы с источником питания или окисленным кабелем данных.
Я занимался программированием на низком уровне, и мне пришлось выключать компьютер примерно 50 раз.
Я предполагаю, что значение 191 G-Sense_Error_Rate
равное 438, вполне подойдет , я думаю, это связано с перемещением ноутбука, когда жесткий диск включен .
Что действительно забавно, так это то, что мой раздел Windows перестал загружаться и не может быть смонтирован на другой машине с Windows или Linux, но он прекрасно смонтирован на OSX, что позволяет мне восстановить мои файлы. Я переустановил и скопировал данные в него с тех пор, и, кажется, работает отлично. OSX находится на другом диске.
