I have a WD Elements with 2 partitions (HFS for Time Machine and NTFS for personal data), the hard drive stop being recognized, under Windows tell that I need to format the driver. I test with S.M.A.R.T and the disk have problems so I decide to use ddrescue under Mac Sierra. I run the following command:

sudo ddrescue -v -n -b 4KiB /dev/disk4s3 /Volumes/Backup/failing_drive_backup.dmg /Volumes/Backup/failing_drive_backup.log

With this command I tried to recover the NTFS partition (350GB), here is a
log of ddrescue.

Now how can I mount the partition or put in other hard drive?

I already created a 350GB NTFS partition on a good hard drive and tried the following command

sudo ddrescue -v --force /Volumes/Backup/failing_drive_backup.dmg /dev/disk4s5 /Volumes/Backup/recover_drive.log

This process ended but I can't open the partition I have tried "EaseUS Data Recovery Wizard" and I can get the some images and files from the hard drive but this process don't organize the images on the folders.

Any idea how can I fix the partition or get the data organized by folders? I have tryed chkdsk but if return

The type of file system is NTFS. The first boot sector is unreadable or corrupted Reading second boot sector instead Unable to determine the version and volume state. CHKDSK aborted.

    I don;t believe you can write a partition image into an existing partition. Its good that you can retireve intact files via a file carving utility, that bodes well for the rest of your data, but it would lose filesystem information. Now it is quite possible that with windows offering to format the disk that the filesystem itself was damaged, so attempt chkdsk on it (before deleting your backup image) to see if it can't be repaired in-place. – Frank Thomas Feb 14 '17 at 19:27
  • If you have damaged NTFS, you might give a try to this solution: askubuntu.com/a/776317/271 It works on macOS as well. – Andrea Lazzarotto Feb 16 '17 at 18:24
