$MFTMirr does not match $MFT (record 0) 解決小記

在 X Window 下卸載隨身碟或是 2.5 吋硬碟,
有的時候會出現 X 很快的又掛載硬碟上來

這個時候如果不小心搶快把 USB 線拔掉
重新連接的時候, 就會出現以下錯誤訊息

# mount /dev/sdb1 /mnt/
$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.

這個時候該如何呢?

有些 ntfs 指令沒機會玩, 現在就有機會啦

ntfs 開頭的指令如下

# ntfs

ntfs-3g ntfscat ntfscp ntfsls

ntfs-3g.probe ntfsclone ntfsfix ntfsresize

ntfs-3g.secaudit ntfscluster ntfsinfo ntfsundelete

ntfs-3g.usermap ntfscmp ntfslabel

看了一下, 應該是用 ntfsfix 比較有可能

所以就試試看

# ntfsfix /dev/sdb1

Mounting volume... FAILED

Attempting to correct errors...

Processing $MFT and $MFTMirr...

Reading $MFT... OK

Reading $MFTMirr... OK

Comparing $MFTMirr to $MFT... FAILED

Correcting differences in $MFTMirr record 0...OK

Processing of $MFT and $MFTMirr completed successfully.

Setting required flags on partition... OK

Going to empty the journal ($LogFile)... OK

NTFS volume version is 3.1.

NTFS partition /dev/sdb1 was processed successfully.

果然順利的解決問題

筆記一下

Sometimes when you unmount flash disk at X Window.

X Window will mount it again quickly.

If you remove the USB cable at the same time.

When you connect the USB cable, you will see the error messages.

# mount /dev/sdb1 /mnt/

$MFTMirr does not match $MFT (record 0).

What would you do at this time?

Some commands which start with ntfs you can use it.
