I am having trouble writing to a few files on an external HD. I am using it to store media files as well as my time machine backup. The drive is formatted as HFS+ Journaled, and other files on the drive can be written successfully. Additionally, the time machine backup is working perfectly.

Permissions for the file:

    $ ls -le -@ Parks\ and\ Recreation\ -\ S01E01.avi
-rw-rw-rw-@ 1 evantandersen  staff  182950496 22 May  2009 Parks and Recreation - S01E01.avi
        com.apple.FinderInfo           32

Things I have already tried:

sudo chflags -N
sudo chown myusername
sudo chown 666
sudo chgrp staff
Checked that the file is not locked (get info in finder)

Why can't I modify that file? Even with sudo I can't modify it at all.
