I have enabled this on my Samsung 830. After a reboot it worked fine. Do I need to add this into my startup items or do anything more, or can I close it and it will continue to work?? ---------- Ignore my question! Once the system is patched its obviously done, so no matter whether you close the Trim Enabler app, or restart etc, it stays patched! If you want to disable Trim simply use Trim Enabler again to unpatch! Duh!
