I try to remove a directory (rm -rf) and I get:

rm: cannot remove 'EMBA': Directory not empty

moreover when I try to list the directory I get:

ls: reading directory 'EMBA': Input/output error

the directory EMBA has 777 as permission and no program is using it.

The operating system is Ubuntu 20.04 and the file system is NTFS.

UPDATE

Following the roaima answer I try to:

1 - Check the recent output from dmesg or journalctl -k to look for messages corresponding to disk I/O errors

I can't find any error messages

2 - Check the SMART attributes to see if the disk is dying, or whether it's just the filesystem (smartctl -x)

I think there is notting relevant

3 - Check the filesystem with ntfsfix. I get:

 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/sdb2 was processed successfully.

4 - Check the filesystem using a Windows OS

Windows has encountered errors on the volume 

After fix the error and reboot the system the error in removing the directory was solved

The filesystem or disk has failed (Input/output error). Things you should try include,

  1. Check the recent output from dmesg or journalctl -k to look for messages corresponding to disk I/O errors
  2. Check the SMART attributes to see if the disk is dying, or whether it's just the filesystem (smartctl -x /dev/sdb, replacing sdb with the correct device name for the disk)
  3. Check the filesystem (ntfsfix /dev/sdb1, replacing sdb1 with the correct device name and partition number)
  4. Check the filesystem using a Windows OS
