ntfsfix to solve the problem of not being able to mount NTFS hard disk under Linux, mainly by the problem of
$MFT file of hard disk partition, you can use
chkdsk command under windows or use
ntfsfix under Linux to fix it.
First the failure details.
$ sudo mount /dev/sda1
$MFTMirr does not match $MFT (record 3).
Failed to mount '/dev/sda1': 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.
Then I saw a similar situation on
askubuntu, and a reply with a high approval rate said that there was a problem with the
$MFT file, which could be fixed using
chkdsk under windows, and I had written a tutorial on how to do it before, but this time I tried to fix it using
ntfsfix under Linux.
Here you need to install
ntfsprogs tool in advance, you can also use
apt to install it directly under ubuntu, the following is CentOS7 as a demonstration.
$ sudo yum install ntfsprogs
$ sudo ntfsfix /dev/sda1
Mounting volume... $MFTMirr does not match $MFT (record 3).

After the repair is complete, we mount it directly and this time no error is reported and we can read and write the files inside normally.
Since the directory and method of mounting is already specified in the
/etc/fstab file, specifying the device number to be mounted directly on the command line will allow you to mount it based on the information in
