If there is any reset key in back side of your smartphone above battery near SIM card slot. Pressing the reset key can also solve the problem without getting into Command Prompt or any professional application software available online.
I own Sony Xperia C with San Disk Class 10' 16 GB Ultra Micro SD card with built-in security system but still it showed this message twice. First time on 22.05.2015, I inserted my SD card into Window phone/ Java phone which can easily read the same card without format and copy all data but that time I need to install the previous applications again. But second time today on 23.06.2015, I tried the reset key which worked and no need of going to CMD command raised.
