    12.10: fstrim -v ALWAYS says "0 bytes were trimmed"

    Hi!

    I wanted to check if trim was enabled for my SSD but it never finds bytes to trim.
    I mounted my home folder in the fstab like this:

    UUID=a112a989-2d8e-43cd-a6b7-2f776402b865 /home ext4 noatime,data=writeback,nobh,commit=100,nouser_xatt r 0 2

    i tried to mount it with the discard option, but fstrim -v /home ALWAYS gives back "/home: 0 bytes were trimmed".
    how else can i trim my SSD? Its no problem if i have to do it manually.

    PS: Its a Samsung 840 Pro SSD in a (2008) Dell XPS M1530.
    PPS: is it possible to trim a NTFS partition under ubuntu?

    Thanks in Advance!

    1. Code:
      man sudo
    2. No.
