I cannot delete .Trash-503 folder via GUI or terminal,
it returns a $RECYCLE.BIN.trashinfo: Input/output error

Not even sudo rm -r or even a simple ls works in that trash directory.

Check terminal output below:

subroot@subroot:~$ cd /media/xxxxx/

subroot@subroot:/media/xxxxx$ rm .Trash-503/
rm: cannot remove `.Trash-503/': Is a directory

subroot@subroot:/media/xxxxx$ rm -r .Trash-503/
rm: cannot remove `.Trash-503/info/$RECYCLE.BIN.trashinfo': Input/output error
rm: cannot remove `.Trash-503/info/found.000.trashinfo': Input/output error
rm: cannot remove `.Trash-503/info': Directory not empty

subroot@subroot:/media/xxxxx$ sudo rm -r .Trash-503/
[sudo] password for subroot:
rm: cannot remove `.Trash-503/info/$RECYCLE.BIN.trashinfo': Input/output error
rm: cannot remove `.Trash-503/info/found.000.trashinfo': Input/output error

subroot@subroot:/media/xxxxx$ cd .Trash-503/

subroot@subroot:/media/xxxxx/.Trash-503$ ls
info

subroot@subroot:/media/xxxxx/.Trash-503$ cd info/

subroot@subroot:/media/xxxxx/.Trash-503/info$ ls
ls: cannot access $RECYCLE.BIN.trashinfo: Input/output error
ls: cannot access found.000.trashinfo: Input/output error
found.000.trashinfo  $RECYCLE.BIN.trashinfo

subroot@subroot:/media/xxxxx/.Trash-503/info$

What's going on here and how can I delete this folder?

EDIT

I tried checking and repairing the partition using gparted only to get this error message:

ERROR: Filesystem check failed!
ERROR: 264 clusters are referenced multiple times.
NTFS is inconsistent. Run chkdsk /f on Windows then reboot it TWICE!
The usage of the /f parameter is very IMPORTANT! No modification was
and will be made to NTFS by this software until it gets repaired.

I don't have windows installed, how can I run chkdsk /f from ubuntu?
