13.10 testing Trim on Intel SSD

[xigen]

I tried to install Trim as a chron job ... unfortunately, when I attempt to test to see if trim is working... $sudo fstrim -v / the terminal does not give any output.

Thoughts?

I tried it again based on this article:
http://www.howtogeek.com/176978/ubuntu-doesnt-trim-ssds-by-default-why-not-and-how-to-enable-it-yourself/

Trim took a minute or two to work.

I thought it would take less time.

Solved.
