I just did the hard reset by BOTH methods described at Hard Reset - DROID BIONIC by Motorola, and my phone STILL had photos and other data left on it. This was with the microSD memory card already removed, so I'm not talking about that external memory, I'm talking about internal. I MAY have still had the SIM card in it when I did this, so that might have had something to do with it, but these methods advertise/warn that they're going to delete everything, and they didn't.
Do not reply and tell me I did something wrong and try to explain anything to me. I am not mistaken. I am posting this as a warning to others NOT to trust either of those reset methods to work - they don't. At least not on my Bionic, which was at Android 4.1.2, the most current version as of today.
Just for completeness, here are the methods I used, copied as pasted from that link as it is today:
