This is wrong because the command chmod had failed to set the permissions
The chmod command is doing the right thing; the problem lies elsewhere.
Run "strace chmod a-r a.txt". You should see something like
"fchmodat(AT_FDCWD, "a.txt", 0200) = 0" which means chmod told the
kernel to change a.txt's permissions to -w------- and the kernel
responded that it did so successfully.
The problem here is a squirrelly filesystem. Run "man ntfs-3g" and look
for "Access Handling and Security".
