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!
