Error when getting information for file – Input/output error

I ran rsync sudo rsync -aE --progress /mnt/seagate/dataset/RD 8* /mnt/backUp/backUp/dataset/ and pressed ctrl-c by mistake. There was a SIG-INT error whic makes sense.
But now, I am not able to access the hard disk mounted on /mnt/backUp.

Whenver I try to access my drive, it says:
This location could not be displayed. Sorry, could not display all the contents of “dataset”: Error when getting information for file ‘/mnt/backUp/backUp/dataset/RD 838Jun05’: Input/output error

output of sudo ll is attached in the image below.
output sudo ll

I tried running :
sudo smartctl -i /dev/sde2 whose output is

smartctl 6.2 2013-07-26 r3841 [x86_64-linux-4.2.0-42-generic] (local build)

I am still able to move the files that were already existing though, which I am assuming, means that only few sectors went bad.
Can you please tell me if there is any way I could fix this? I am not able to do ntfs-fix as well
