I have an external USB drive that I have added via the SNAP plugin.  The problem I am having is that I cannot chmod or chown the files on the drive mounted by SNAP.  The command appears to work just fine, but when I do an ls -al on the directory afterwards, nothing has changed. I could get around needing to chown the directory if I could get chmod to work at the very least.  How can I get around this issue?

 

For example here is the output of:

ls -al /mnt/disk/Backup/Movies/Librarian\ The\ Curse\ of\ the\ Judas\ Chalice\,\ The\ \(2008\)/

 

total 4586940
drwxrwxrwx 1 root root          0 May 19 13:21 ./
drwxrwxrwx 1 root root     237568 May 15 10:11 ../
-rw-rw-rw- 1 root root 4695925322 May 18 23:59 The\ Librarian\ The\ Curse\ of\ the\ Judas\ Chalice.mkv

 

Then I run this command:

sudo chown -R -v nobody:users /mnt/disk/Backup/Movies/Librarian\ The\ Curse\ of\ the\ Judas\ Chalice\,\ The\ \(2008\)/

 

This is the output:

changed ownership of `/mnt/disk/Backup/Movies/Librarian The Curse of the Judas Chalice, The (2008)/The Librarian The Curse of the Judas Chalice.mkv' to nobody:users
changed ownership of `/mnt/disk/Backup/Movies/Librarian The Curse of the Judas Chalice, The (2008)/' to nobody:users

 

Immediately after running that command:

total 4586940
drwxrwxrwx 1 root root          0 May 19 13:21 ./
drwxrwxrwx 1 root root     237568 May 15 10:11 ../
-rw-rw-rw- 1 root root 4695925322 May 18 23:59 The\ Librarian\ The\ Curse\ of\ the\ Judas\ Chalice.mkv

How is the disk formatted?  What file system?

df -T lists it as fuseblk, so NTFS I would guess

The SNAP UI will tell you the format.

 

NTFS doesn't support extended attributes.

Cp to the array and then change owners.
