NTFS盘 挂载不上,郁闷，救救我吧

ringfin

archlinux  NTFS盘 挂载不上.我的电脑是单系统archlinux，已经把原来的windows格了，结果原来的E盘，也就是sda4挂不上去了，用ntfs-3g提示是unvalid NTFS, 郁闷了~~~~~帮帮忙！！！
  有一点很奇怪，用fdisk -l 显示sda4为NTFS，而blkid显示sda4为ext4

[jing@DELL ~]$ sudo ntfs-3g /dev/sda4 /mnt/file
NTFS signature is missing.
Failed to mount '/dev/sda4': Invalid argument
The device '/dev/sda4' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

fdisk里的分區類型是可以修改的，只是作為一個標識——其實你設成什麼都沒有關係。而且，只有設為HPFS/NTFS時，才可以被Windows自帶的磁盤管理功能修改（格式化等操作）。

blkid的類型是對文件系統進行檢測後得出的，應該是正確的。
