Problems changing file and directory permissions using chmod
I'm having trouble changing permissions in any directory or file, specifically to execute. Here's some info from my terminal and what's happening:

As you can see, none of the permissions have changed
I've also tried several different parameter number and letter formats after chmod including but not limited to: 777, 544, go+x, and several others.
The perms you are 'seeing' are Linux's interpretation of NTFS perms (sort of).
Basically, each file-sytem type eg ext3, NTFS has its own unique idea of 'perms'.
The best thing to do is change them in /etc/fstab ie at mount time, as ext3 perms != NTFS perms.
If it is a NTFS disk check the mount options and check if it is mounted with ntfs or fuseblk(ntfs-3g). The standard ntfs driver is read-only. You need the ntfs-3g driver if you want rw access.
