Re: "uh oh"

I came to this site 2 find a soution and discovered 1 on my own. I have downloaded music on my PC. So I opened the folder with the music in it then I opened the folder that the Shaker is associated with (being plugged in via USB) and I clicked & dragged the songs into the folder. Both of my daughters have the Shaker. It works now and we are ALL happy....

Hope this helps... Gail

Re: "uh oh"

The music has to be in MP3 format.

If you have copied CD's to your computer, you will need to change the settings in Windows Media Player to copy them as MP3's.

Windows Media Player>Tools>Settings>Rip Music (Copy Music)>Chane Rip Music as to MP3.

Delete all the songs you copied before from your computer and from the Shaker.

Copy the new songs back to the Shaker after you change the settings.

Best of Luck.

My sansa shaker is just not playing any music

"Media Coder" is a free program you can download that will convert your songs on the shaker to MP3 files. I had the same problem. Make sure the shaker is plugged into computer so that you will be able to choose the songs on it to convert. Very easy to use. Just google "Media Coder" and you should find it.

Loading songs

check the file types from you music the shaker only plays MP3 and PCM WAV  file types. You may have WMA (if u used windows media player) which will not play on the shaker  (i had this same ploblem btw) you can easly find free music file converter software to change these files to mp3 or wav types (which i did), or you could rerip to songs from a cd and tell the windows media player to rip the files as mp3 types instead of the default wma format  from the windows media player widow :
tools >> options >> Rip Music >> under format select mp3 (theres a wav option but i used the mp3 option to be safe) 
do not use the sync feature it will automatically convert your files to to wma (why? i dont know) instead copy the files directly from the folder that contains them :
right click the file you need to put on the player select open file location drag and drop to the player (or copy/paste if you want).
hope this helped =P

Sansa mp3 shaker

First, don't plug the shaker into the computer, go get an SD card reader available pretty much anywhere, I use a Targus reader that turns an SD card into a USB thumb drive, before I got it (it was $8.88 at wallyworld(Wal*Mart)) I used a multimedia reader.

First thing you do, format the card, and make sure the MP3 files you put on the card are at least 128bit, Constant Bit Rate (CBR) [DO NOT USE VBR, IT WILL CRASH THE PLAYER], High Quality, Stereo, Original.

You can get these settings with the LAME encoder that adds on to AudioGrabber when you rip a disc. (Both AG and LAME are FREEWARE)

I have not ever had my shaker connected to my computer(s), just the cards, and I use mine daily at work to keep me sane, and I switch the cards a lot.

I do hope this helps!

Hi my sansa shaker wont play music

The Sansa Shaker ONLY plays MP3's, I downloaded a bunch of .wma files and kept getting the uh-oh so I put on an mp3 I had a voila! it played. Bummer though. Guess I gotta figure out how to convert my music files for my daughter, or pitch this thing and buy one that will play any media file.

It can only be mp3 format. ONLY MP3. Convert all your music to this format only using this website:
be patient the site is very busy
Even if your file has been renamed to a mp3 file it will not work until you convert the files.
I have 2 of these and had to do this with all my music. Then after conversion click and drag the songs.

Help Me! Sansa m240 say only 'Finalizing Update" then turns off

Oh lol this is easy. just go onto realplayer or something then go on the tab burn/transfer then it will tell u your songs delete them all. then try turning your mp3 on and going to "settings" then go all the way to the bottom of that page then click "reset all" then go back to windows media player and put your songs on.
