デュアルブートWindowsとUbuntu、しかしUbuntuはWindowsパーティション `/dev/sdb3`にアクセスできない、次のエラーメッセージを表示する:

Error mounting/dev/sdb3 ...
status 14: The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Failed to mount '/dev/sdb3': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option.

解決策

何が根本的な原因であるかわからない、Windowsが正しくシャットダウンしなかった可能性があります。それを修正するには、 `ntfsfix`を使ってNTFSディスクをチェックし修復してください。

$ sudo ntfsfix/dev/sdb3
