Question about Digital Audio TRIO MP3 Player

Trio Mp3 Player (Red)

Here's the story:
I had 102 audio files and 1 text file on this player when suddenly, without any warning, I turn it on and it displays a message saying: "*No files*". When I try to look at it on my computer a box pops up saying "J:/ is not acccesible. The request could not be performed because of an I/O device error." What the heck??

Help! Do I have a virus? Is it just a crappy mp3 player that isn't worth 20 bucks? Is it safe to plug it into my computer? Can I get my files back? Do ipods do this too? And, What is an I/O device error?

    Trio says "No files"

    I have the same problem. The many existing files suddenly and mysteriously went away. The normal display says "No Files". The "About" display says 000 space used and 000 space available. When the Trio is plugged into a computer, it is recognized as a USB device, but Windows issues an error dialog saying it is unformatted and asks if I want to format. When I click yes to format it, Windows says it can't be formattted.

    Same problem. It happened after i left it plugged into a USB port for a couple of days. The battery wore down completely, and ever since, it hasn't maintained any files. It doesn't even work as a thumb drive anymore. At one time, it would still work when plugged into my car stereo. However, now I can't access it at all.

Download the current firmware version from the mach speed website (you should be upgrading to version 011.620.130). I had to install it 4 (four) times before it finally took. The only way I could make it work was by checking the "Format Data Area" box. Unfortunately, this causes you to lose all info stored on (in?) it. You'll know that it took because a dialog box will open telling you that the player has been reset, and that you need to disconnect it so it can restart.

Got a solution--at least a temporary one. Try plugging it into your computer's USB port and seeing what drive letter is assigned to it--on mine it's G:. Then open up the "Run" tab under your start menu and type "format G:" Once it's formatted, it will take files again. The only trick is, they'll probably go away if the battery runs down again.

Mine wouldn't even turn on when the drive was unformatted, but once it was formatted, it worked again on battery power.

    OK, it's a VERY temporary solution. It lasted a total of eleven songs, at which point the memory card crapped the bed again. Windows can't access it anymore, there's no formating at all, and it needs to be reformatted. Which means I spent over an hour transferring files last night for nothing.

    These are not a good product.




Just f*** it

Ok, my model of the Mp3 came with a disk, i know what the disk is used for ( to allow the electronical device charge) but when i went to upload the disk my fire wall came up and said "warning malware...

Hi, it wont be a problem its just giving you that warning as the device is not on any list to say its safe, so your computer gives you a warning as its something it has never heard of, you will have no problems using it it happens quite a lot when you buy devices that are not from well known makers.
so just run the disk and click ignore the warning and it will then load as normal and it will then let you access all the info on the mp3 player.

have you tried connecting the mp3 player without the disk installed just to see if you can access the files without having the disk installed. your computer may pick it up and let you put music on without the disk, it might be a bit harder and take a few goes to get right or just use the disk and do it the way it says in the manual

using the disk will not harm your computer or your files, if it was something you was downloading or a disk someone had copied for you then i would say dont use it but as its the original disk you will have no problems and you can then use your mp3 player

hope that has stopped your concerns

You can convert your AVI files to one of the files supported by your player by using the free software download at:

According to what I have read this player will support MP1, MP2, MP3, WMA, and WAV audio formats and SMV video format

Good Luck,
I hope this helps

Playing of audio books on mp3

hi mag_dan,

your mp3 player may only support sound files of the wma, mp3 and wav format, therefore the audio book files should be tranferred/converted into one of these these formats.

try using the software provided here to do it:

and then send the converted files to your player and enjoy listening!
