I just upgraded to Windows 10, and I noticed the SSD optimize tool is SSD trim. However, after I ran the SSD optimization showing 100% trimmed, I noticed the trim didn't work because I could still recover my deleted files via data recovery software ( I had win 7 before win 10). In addition, I also noticed I could recover my old files I deleted back to 2013. Does it mean TRIM function will not wipe the block unless I do secure erase on the SSD?
