I don't notice any mention of file shredder software. I have never used one, but there is freeware available that purports to wipe individual files. If that's true, it seems to me (in my ignorance) that it shouldn't interfere with the ability to recover other files.
Also, to state the obvious: never keep any data on your OS drive that a repair technician might find, er, entertaining.
For all pedophiles: please ignore that advice. No repair tech would ever dream of turning you in.
