本文讲述当你怀疑自己的硬盘出现某些问题时,如果对其进行检测.

简述

当你通过计算机存储你的图片或文档文件时,它们将以某种形式记录在你的物理存储器上.比如转化为磁性信号然后存取于硬盘上,或是通过光信号存取于光盘上,或是转换为电流信息存取于U盘.无论是哪种方式,都可以把它比拟为是往某个文件柜中存放文档.

任何事物都不是完美的,你有可能会碰到两个问题:你的文件丢失-你的文件变得无比混乱,甚至根本无法正常读取,或者是你的存储介质发出故障-比如硬盘坏道,光盘腐蚀.

当然,当遇到这些情况的时候,有些工具是可以帮助进行错误检测和修复的,本文就是向你介绍这些工具,以便在你发生上述不幸时给予一些帮助.切记,要经常在一个独立的设备上备份你的最新文件.

检测文件系统

On occasion, errors may occur in the data stored on a disk. This may be due for example to power failures, system crashes or impetuous removal of media. When this happens, files may become lost or corrupt - you will need to check your data for validity.

The tools used to check your data depend on your filesystem, please refer to the approriate section.

ext2 and ext3

In a terminal run :

man e2fsck

to consult the documentation related to testing there partitions.

FAT32和FAT16的检测

To check and repair MS-DOS type filesystem, we will use the dosfsck tool. In a terminal, type the fooling to know the name of the partition you want to check :

sudo fdisk -l

No we will run the check with the following command (assuming your partition is /dev/hda1) :

dosfsck -a -v /dev/sda1

The a option is use to automatically repair the file system.
The v option is use to get some more information about the check.

You may have a look at :

man dosfsck

to get some information about the others options available.

NTFS的检测

Their is no equivalent yet to chkdsk/scandisk for NTFS in linux.

The linux-ntfs team project to make one.

Check http://wiki.linux-ntfs.org/doku.php?id=ntfsck for the current status of the project.

In the meanwhile, you'll have to use windows to check your NTFS partition.

Checking for Physical defects

In a terminal run :

man badblocks

to consult the documentation related to testing disks.

数据恢复

TestDisk is a tool for recovering lost data, click on the previous link to visit their website.

-When you store your files, be they pictures or text, they reside on a physical media. They can be magnetically coded on the surface of a hard disk, etched and optically read from a CD, or electrically stored on a USB flash drive. Using these methods, your files are organised in a way analogous to placing files in a filing cabinet.

-Nothing being perfect, there are two problems that may occur : your files may become lost - a corrupt index meaning that all the pieces of the files are so muddled up they no longer make any sense - or the storage media may develop defects - bad blocks on hard disks or scratched CDs.

-Of course, in case this should happen, tools exist to detect and repair errors. We will present these tools to you now, in the unlucky event you will need them. Remember, always backup your files on at least a separate media.
