The test_trim.sh test doesn't return the all-zeros result that it should. The sector data are unchanged.
I double-checked my fstab modifications, rebooted and retried the test script.
The SSD drive is a Kingston sv300s3. I'm running the 32-bit version of Linux Lite 2.4 on an Asus X101CH eeePC.
McDivot may be right that trimming doesn't happen automatically, you have to request it. I probably won't bother. The idea that my SSD might last longer was the motivation for trying the fstab mod.
Linux Lite is a fine distro, by the way.

The Trim tutorial has been re-written with new information and will appear in the new Help Manual when it is released.

I don't use the automatic fstrim, I do it manually.
To clean junk I use the terminal every now and then and enter the following,
e.g:
for root partition: sudo fstrim -v /
for home partition: sudo fstrim -v /home
You can adapt this for any other partitions, e.g. data partitions..
I picked this up from Quidsup on Youtube.
