Casio PX-5S No Media Error

A customer recently came to me with a Casio PX-5S that displayed “Error: No Media” after booting, and which wouldn’t produce any sound.

The Problem

The customer had already researched the issue themselves, and they had determined they needed a firmware update. He’s not alone, and Casio helpfully provides the following message to those with similar struggles: “Well, we’re not 100% certain. […] Casio has worked very hard to try to replicate this problem on units that have exhibited this behavior and have never been able to replicate it.” (See their post on Casio Music Forums.)

The Solution

The firmware can be downloaded from my MEGA directory here, if you’re looking for the PX-5S firmware specifically.

Alternatively, you can download the zipped archive from Casio directly. You’ll need to extract it.

Once you have the “update.bin” executable file, either by downloading it directly from me or by extracting their archive, you’ll put that file into the root directory of a USB stick.

Note that the USB stick must be formatted FAT32—the keyboard cannot read NTFS or exFAT.

If you download from Casio, do not put the ZIP file on your USB. Only the “update.bin” file.

At that point, you can simply plug the USB stick into the keyboard, and the update will automatically begin. It takes about fifteen minutes.

  1. I’ve had my PX5S in the closet for a few years now. I fired it up today, and got that error message. I Tried everything suggested, and still nothing. Then, I realized that I’d downloaded more than one copy of the firmware update. On my Mac, this adds a couple of numbers to duplicate files. I deleted those extra copies, and downloaded a “fresh” copy from Casio – et voila! The firmware update worked as advertised. Just be aware that your thumb drive has to be formatted in FAT32 – not exFAT32. Also, remember to extract the .bin file from the .zip download. Then, load the .bin file onto the root directory of your thumb drive. Plug it into your PX5S, sit back, and wait. It takes a few minutes, but you’ll see the patch indicator LEDs light up, one at a time, as the files load. Although I use the latest and greatest software instruments, the CASIO sounds are really very good – more than adequate for live performances – even recording. Good luck.

    • Hello Dickie, and thank you for the input! That’s very good advice, and I’ve added a couple of notes accordingly. The formatting of the USB stick is especially important, and this seems to be a common hazard. Enjoy your PX5S!

  2. hello, I don’t know if anyone will still be monitoring these pages. I did everything as directed, and it starts uploading the data, however when it gets about halfway done, it shows a wrong data message. Am I missing something?
    I’ve extracted the .bin file
    I’m using FAT32
    I don’t have any other files on the usb
