No USB Mass Storage - how else can I recover lost files?

view story

http://forums.androidcentral.com – Hi all, I have seen this question posed in the S4 forum but couldn't find any discussion about it amongst my fellow HTC One owners, apologies if it has been discussed, if you would be so kind as to point me in the direction of it then please let me know. If this point hasn't been raised - is no one else experiencing problems because it is no longer possible to mount the phone as a mass storage device? I stupidly deleted a photo that I would really like to recover (i swear its not boobs!) and have now tried to use 3 different programs to recover it - Wonderphone, Yodot and Stellar Phoenix (HowTos)
