Bad Sectory

[Nickolas]

Dobry ! :P

 

Mam pewien problem z dyskiem (znowu) w laptopie ... Otóż, Ubuntu wykrył, że mam Bad Sectory - znowu ! :o 2 miesiące temu dostałem laptopa z naprawy, bo były bad sectory i dali mi nowy dysk - a tu proszę znowu ! Oto screeny:

I co w związku z tym? Idź znowu do serwisu.

[Nickolas]

Ok, ale chodziło mi oto, czy to jest coś poważnego - zapomniałem to popisać na końcu posta ;)

[Ranmus]

Tak, jest to poważna sprawa, bo oznacza że dysk jest zbyt awaryjny. Przekroczyłeś dopuszczalną normę bad sectorów i jeśli dysk jest na gwarancji, to producent powinien Ci go wymienić / naprawić. Ja przykładowo mam 2 dyski seagate 500GB na gwarancji z ponad 300 bad sectorami każdy, ale tyłka mi się nie chce ruszyć by je wysłać do producenta. :)

 

Najlepiej to zapuść w konsoli komendę i wklej tutaj cały wynik (bo warto sprawdzić czy mechanika też nie jest przypadkiem jakoś uwalona):

smartctl -a /dev/sda

[Nickolas]

O to co mam przez wpisanie "smartctl -a /dev/sda" trochę długa lista ;)

A i jeszcze chciałbym dodać, to to że jak uruchomię ubuntu, to samym początku, pisze mój akumulator jest za stary albo za słaby, bo jego Pojemność: 47,1% :/

 

A tak w ogóle - jaka jest norma bad sectorów ?

[Ranmus]

Akumulator - a po załadowaniu do 100% i restarcie z odłączonym zasilaczem dalej masz 47%?

 

Dla tego dysku dopuszczalny limit bad sectorow to 100 (kolumna value).

[Pieter]

czyli bad sektory to uszkodzenia fizyczne? nie da się ich naprawić domowymi sposobami?

 

nie ważne, już przeczytałem i rozumiem.

[Nickolas]

@ Ranmus

 

No niestety tak ;/

 

EDIT:

 

Czasami piszę, że akumulator nie jest podłączony a świeci się dioda na laptopie, że jest podłączony :/
