Update your keyboard to the latest firmware V1.13.  Now leave that USB drive plugged into the keyboard at all times.  This will prevent the error message.  Initialize ALL is not necessary.  You user data will remain intact if you do not perform initialize all. 

I have done all this at least 10 times in the last 2 years for this I can say that I will not buy more casio products, cheap yes but they do not works !

Thank you

Casio PX5 S - randomly lose every sound and need a reboot ... not acceptable for a 800 euro ... and for sure i'm not alone

p.s  ...... Joe you are wrong :-)

Random "no media error " Still occur . 
Never buy casio products
