Perfect.  Took card put old 32gb card and transferred it over to it in the computer.  (while my Samsung galaxy s5 was off).  Then inserted it in my Samsung galaxy s5, powered up and it was like I had never took the 32gb card out.  Read ringtones, programs stored on external sd card, everything - no errors, no glitches.  Connected the phone to the computer via usb cable and (usb 3 slot) and in no time my 75gb of music was transferred to my phone and it all read and is working perfectly.  I could not be more pleased when a products works like it is supposed to.
