ubuntu 拷贝文件中断后无法识别硬盘分区

• 今天我用移动硬盘在Ubuntu 12.04拷贝数据，可能是系统响应过慢，拷贝到最后时未完成，就将硬盘移除。下次再插入硬盘硬盘时提示：
  

“Error mounting: mount exited with exit code 13: $MFTMirr does not match $MFT (record 0). Failed to mount '/dev/sdb1': Input/output error 
NTFS is either inconsistent, or there is a hardware fault, or it's a 
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows 
then reboot into Windows twice. The usage of the /f parameter is very 
important! If the device is a SoftRAID/FakeRAID then first activate 
it and mount a different device under the /dev/mapper/ directory, (e.g. 
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details.”

• 多次卸载再插入也挂载不成功，于是按照提示去解决问题。

• 先在windows server 2003上尝试用chkdsk /f命令去修复硬盘错误，但用 echo list volumn|diskpart 命令查不到该移动硬盘的卷名，查询结果如下：

C:\Documents and Settings\Administrator>echo list volume|diskpart
Microsoft DiskPart Copyright (C) 1999-2001 Microsoft Corporation.
On computer: SCUTECH-LZX
DISKPART>
  卷 ###      Ltr  卷标         Fs     类型        大小     状态       信息
  ----------  ---  -----------  -----  ----------  -------  ---------  --------
  卷 0                                 磁盘分区       466 GB 状态良好

  卷 1         D                       DVD-ROM       0 B 状态良好
  卷 2         C                NTFS   磁盘分区        40 GB 状态良好     系统

• 于是又在windows server 2008尝试修复。发现移动硬盘可以直接在该系统打开，查看到是D盘，于是修复D盘的移动硬盘，修复过程如下：

C:\Users\Administrator>chkdsk D: /f
The type of the file system is NTFS.
Volume label is Seagate Backup Plus Drive.

• obackup-2.1.904-ubuntu-12.04.1-server-amd64就是我之前拷贝出错的数据，现在将其index entry删除。
• 重新将移动硬盘查到Ubuntu上，已经可以重新挂载并使用了，就这么简单～
