Problem in sofware

registeer it they will send u a new one

If your music has DRM it willonly allow you to sync once. they want you to repurchase the music. Try syncing music that is DRM free. If the new file work that is your problem.

Down load the firmware on Sansa's website. I have a Sansa 250R and it wouldn't work with the new replacement usb (Griffin) cord I bought at Best Buy. So I bought a Sansa Fuze and the cord that came with it worked on the E250R. Huh? Yeah, go figure...and oh, that replacement Griffin usb cord I bought worked fine with the new Fuze. I came real close to buying a new battery for the E250R but instead invested that money in the Fuze.

I think you should takle your mp3 back to the store you bought it from and get a refund. To be honest sansa mp3s ****. and herer another advice for you my friend:
"Never buy a sansa mp3."

You have to synchronize your Sansa to a computer that has a current subscription to Rhapsody, and you have to sync the Sansa to that same computer at least once every 30 days, or the Rhapsody songs will stop working. Use a different music service that is free, or convert all of the songs to Mp3 format to get around the problem. If you get a subscription to another music svc, then you must maintain a current subscription with whatever new svc you choose as well.

First you Have to make sure you have a sacure and strong connection with you computer then it will work. i had the same problems when i first bought the sansa

the best way for that is to read your manual.

MINIMUM SYSTEM REQUIREMENTS
Windows XP SP1
Windows Media Player 10
Intel Pentium class PC or higher
CD-ROM drive
USB 2.0 port required for hi-speed transfer
CONNECTING AND TRANSFERRING
Connect to your Computer
1. Connect the small USB Cable Connector to the USB port on your computer, and then plug the larger
Cable Dock Connector in to your Sansa c200 port.
2. Once connected to computer, it should be detected by the operating system automatically and is
shown as an additional drive called “Sansa c200”.
SANSA MEDIA CONVERTER
You will need to use Sansa Media Converter to transfer photos to your Sansa c200. Insert your SanDisk
CD and select Sansa Media Converter to install it to your PC. Then you can load your personal photos
onto your Sansa c200 by using Sansa Media Converter.

TRANSFER MUSIC
To transfer music to your Sansa c200:
1. Connect Sansa c200 to the computer.
2. Drag and drop files from your computer to Sansa c200 by using a variety of music software
programs to transfer/synchronize your files.
3. In MTP mode as long as the files are WMA or MP3, they can be dragged into the Media folder.
Otherwise, they can be dragged into the Data folder (these files will not appear on the player).
4. In MSC mode, files/folders can be dragged/copied to the device.

That's a pretty weird problem. The only suggestion I can give you is to check to make sure the music you put on was 1) in mp3 or wav format and 2) if this is music you have purchased, to ensure you have the rights properly set to play the music

I'm having the same problem! I've had my Sansa e130 for exactly one year today. I loaded new music on it last night and when I tried to turn it on, it said "searching internal memory for new music." I left it on and this morning it wouldn't come back on with new batteries or even when hooked to a computer! I sent an e-mail to the company for help since there is no reset button. I haven't heard anything yet. I suggest you contact SanDisk too. They may have a problem. And I can't believe someone actually suggested as a solution to put a new battery in it or hook it up! No duh! We're looking for real help here, not the obvious things to try.
