今日在拷貝文件時，可能是沒注意到文件還沒寫入Ｕ盤，強行將其拔出，不料卻出現無法掛載的情況：
Error mounting /dev/sdb4 at /media/xxx/xx: Command-line`mount -t "ntfs" -o"uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177""/dev/sdb4"
"/media/eden/文檔"' exited with non-zero exit status14: The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Failed to mount '/dev/sdb4': Operation not permitted
The NTFS partition is in an unsafe state. Please resume andshutdown
Windows fully (no hibernation or fast restarting), or mount thevolume
read-only with the 'ro' mount option.
究其原因，估計是拔出時文件還未寫完，出現故障，逐步排查如下:
１、打開終端，輸入sudo fdisk -l 可列出所有的分區情況，找到自己Ｕ盤的分區；

2、得知分區爲：/dev/sdb4，創建掛載目錄：
sudo mkdir /media/xxx/yyy (xxx爲用戶名，yyy爲掛載的Ｕ盤的名字)
３、掛載Ｕ盤：
mount -t ntfs-3g /dev/sdb4 /media/xxx/yyy/ -o force
如此做之後，還是會出現錯誤:
$MFTMirr
does not match $MFT (record 0).
Failed to mount '/dev/sdb6': 輸入/輸出錯誤
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.
４、還是不行，網上一搜，用以下命令，大功告成：
sudo
ntfsfix /dev/sdb6

看來以後自己得小心插拔Ｕ盤了。
