I don't know about  Ubuntu wiped drives, (and don't know the best app to 
recover data anyway) but I do a regular wipe of (free space) on my windows 
drives (yes I know it "may" reduce disk life) and the other day I ran a 
recovery app to get a recently deleted txt file, app reads header so txt 
includes most text content file types like:- 

text files: txt, html, asp, bat, C, jsp, perl, php, py/emlx... scripts

(that is why I don't usually try for txt type) , long story short, I forgot the 
app was running in the background, and left it for a few hours, it didn't find 
the txt file I wanted, but it did recover a number (in the 1,000's) of other 
files that I had not seen in years, so even after a good wipe it can happen (at 
least on windows)
