Recently I changed my OS from Windows 10 to Ubuntu 18.04 LTS.

After installing Ubuntu on SSD disk and installing other drivers, everything was well. But when I tried to access my files on HDD hard drive these things happend:

In windows HDD disk had 2 partitions A, E.

In Ubuntu Partition A is mounted well!

But I can't mount Partition E.

Also about 200 Gb of HDD disk is unallocated!

Here is my Hard Drives Info:

sda                              931.5G 
├─sda1      ntfs     Projects    244.1G /media/mehdi/Projects
├─sda2                           195.3G 
└─sda3      ntfs     Other Files 492.1G 
nvme0n1                          119.2G 
├─nvme0n1p1 vfat                   512M /boot/efi
└─nvme0n1p2 ext4                 118.8G /

As you can see sda1 is mounted but sda3 is not.

I tried ntfsfix to fix sda3, result is:

Mounting volume... OK
Processing of $MFT and $MFTMirr completed successfully.
Checking the alternate boot sector... OK
NTFS volume version is 3.1.
NTFS partition /dev/sda3 was processed successfully.

After running command sudo mount /dev/sda3 /media/mehdi/Files :

ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to calculate free MFT records: 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.

  • I did a little research on the problem. ntfsfix is OK, but does not have all of the capabilities that Microsoft's chkdsk does for handling NTFS partitions. You might by able to load Windows into a VM, allow it access to the partition, and be able to run chkdsk from there, or you might by able to boot from a Windows repair disk and run chkdsk from that. I did, only once, manage to install a version of Windows on USB – Charles Green May 9 at 18:29
