Possible to recover deleted files from ext4 SSD?

I've deleted some private data about myself. Didn't want to erase because of inconvenience and lower SSD life.

 

possible to recover maybe by some highly trained technician with adequate software/hardware that has access to it (drive itself). Otherwise not likely as you keep using it

 

Thought so. Googling it results with almost nothing even related to my question.

 

This thread may be of interest.

 

Interesting. Guess I'll try TRIM out later.
Does hdparm support this feature on Ubuntu Lucid ext4?

 

I always try to get as much TRIM as possible. I am always on the look-out for TRIM.

 

Spending lots of time at the skinny model sites are we?

 

Tried out this tutorial, but didn't make it past step 2.
Returned with this error: SECURITY_SET_PASS: Input/Output error.

When I used the command "hdparm -I /dev/X", it did not display a "Security:" section on my SSD.

Does that mean it's not supported?
