My sandisk sansa m240 not working with my windows xp pc

La compania Sansa tiene respuestas a varios problemas en espanol en este link: http://kb-es.sandisk.com/app/answers/list/search/1/kw/sansa%20m240%20manual , Quizas se encuentra alli una respuesta.
Paara pensar en soluciones a su problema hace falta mas informacion: el tipo de pc que esta utilizando (mac o windows, si windows, cual systema - windows xp, vista o windows 7?). El aparato m240 se enciende y reproduce la musica que ya tiene?
Hay dos modos de conectarse el m240 a un pc: MTP (Media Transfer Protocol) para sincronizarse a traves de un servicio como i-tunes, y MSC (Mass Storage Class), que actua como un usb Flash Drive en la compu. Posiblemente su m240 esta en modo MTP y si lo cambia a MSC se reconoce por el pc (vea http://kb.sandisk.com/app/answers/detail/a_id/207/kw/m240 en ingles).
Quizas si pregunta de nuevo en ingles recibira mas respuestas que le ayuden: My Sandisk m240 is not recognized by my pc, or does not appear in My Computer when connected to my pc.

Uninstall/remove the mp3 player from the device manager of windows while its plugged into you computer and unplug afterwards from your usb port and plug it back in, windows now sees a new device and starts installing it.

Go to the configuration panel\system and click at the tab hardware and klik at the button device manager.

This should solve the problem.

Succes.

That model is not fully compatible with vista. So either it works or it doesn't. if not go back to using it on an xp machine.
Thanks,

No driver is needed, Windows XP has native support for this device if you are current with your Windows updates. I have used three different players this exact model. All you must do is connect the device to your PC with a USB cable and it shows up in My Computer.

If you are not current with your updates, go to http://www.windowsupdate.com/

Uninstall all Sansa software and reinstall it from CD.

If that fails:
These are the most common methods for recovering Sandisk's Sansa Mp3 Players. I have been almost universally successful in recovering Sansa players using one or a combination of these methods. These methods do not work if you are having synchronization or music format issues - they are for recovering a player that will not power up, freezes, flashes, is not recognized by the computer, and a host of other issues.

Reset the Sansa Player first. On most models, restart is done by holding the power button in for 15 seconds or longer. Check your specific manual to be sure. The manuals are available from the Sansa website if they have been misplaced.
Download the Sansa Recovery Tool from the Sansa website.
Format - Erases Everything: Connect your Sansa player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "Sansa 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
Firmware Upgrade- Erases Everything: Get the latest firmware upgrade from Sansa - it updates the firmware and erases every song in the player all at once. Note: this method doesn't work if already have the latest firmware. Go to this website and click "Firmware Updater" to find out: http://www.sandisk.com/DriverDownload/driverList.asp
If these fail, then:
Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.
If you get the problem where MTP Device keeps popping up continuously, uninstall the “MTP Device” by going to Start à Control Panel àSystem à Hardware à Device Manager (you computer may vary slightly, depending on Windows Version).
You may have to restart your computer after each of these methods to get them to work properly. Disconnect your Sansa player BEFORE shutting down your computer.

I have had the same probmlem but I've begun to realize that windows vista isn't compatible for the MP3 player when I tried using it with Windows XP -- and it worked fine.

ENGLISH
I had the exact same problem listed in this thread.
This is what I found on another site to fix it.
Make sure your M240 is not connected to the computer.
Then go into the "settings" menu and then go to the "usb" part.
Then Select "MSC" from the menu, instead of "Auto Select (or something like that).
Then turn off your player and connect it to the Win XP computer and it will be fully recognized
and you can then go to My Computer and see it there and use it.


SPANISH
Tuve exactamente el mismo problema mencionado en este hilo.
Esto es lo que he encontrado en otro sitio para arreglarlo.
Asegúrese de que el M240 no está conectado al ordenador.
A continuación, entrar en el menú "Configuración" y luego ir a la "usb" parte.
A continuación, seleccione "MSC" en el menú, en lugar de "Selección automática (o algo así).
A continuación, apague el reproductor y conéctelo a la computadora Win XP
y se reconoce plenamente y se puede luego ir a Mi PC y ver que hay y lo utilizan.

To those that are having problems with the MP3 player not being recognized. With Windows XP there is a little Icon on your Systems Tray that is called the "Safely Remove Harware Icon". Not using this Icon when unpluging MP3''s or zip drives can cause your PC to no longer recognize it. Toshiba Satellite laptops are known for this, others probably have the same problem. The solution here is to install the latest update of the ACPI Flash Bios for the Toshiba Satellite computer. Maybe this is also the problem with other PCs. To prevent these problems allways click on the Safely Remove Hardware icon before removing the MP3 player or any USB flash drive
1 With your m240 set to MSC and connected, go to "My Computer" and "right click" on the "Sansa m240" icon and select "Properties"
2 In that window, select the "Hardware" tab
4. In that "All Disk Drives" window, highlight the "Sansa m240" drive and select "Properties" (at the bottom)
5. In that window, select "Policies"
6. And there, set it to " Optimize for Quick Removal" and click OK and OK again

to old for vista to recognize

Thank you for contacting SanDisk Technical Support. It is our goal to make sure you have all the resources you need to get the most from your product through your recent inquiry into our product line. We do apologize for any kind inconvenience this issue is causing you. For verification, does your computer have Windows XP as its operating system? This issue may be due to some sort of corruption on the Sansa m240 itself. We should try formatting the Sansa m240 as a possible solution. Caution: Formatting will erase all information on the Sansa mp3 player. Please be sure to have a back up of all the information before proceeding. If your Sansa m240 is currently frozen, please remove the battery (to unfreeze it), then put it back in, and connect it to your Windows XP computer. Since you cannot access your Sansa m240 to convert to MSC mode, please have the ?HOLD? button ?ON? so that you can have your Sansa m240 in MSC mode before plugging to your computer. To format the Sansa m240 on your PC, let us connect the Sansa m240 to your computer on an USB port preferably located near the power hub or to an external self powered USB hub, go to ?My Computer?, single right click on the ?Removable Disk? associated with your Sansa m240, and select ?Format?. Let us please make sure that, under FILE SYSTEM, we change FAT to FAT32, and then single left click ?Start?. This will erase all data off the Sansa m240 and correct errors on it, which should make the Sansa m240 usable again. We also recommend formatting the Sansa m240 another way. Please be advised again that formatting will erase all data. Please right click on my computer and select ?Manage?. When ?Computer Management? comes up, please click on ?Disk Management? on the left hand side. After clicking on ?Disk Management? you should now have a list of drives in the right side panel. On the right, look for the Sansa m240, it may show up as Disk 1, 2, 3? Removable Disk. Right click on the larger "Volume" rectangular icon to the right of the Removable disk and select ?Format? choosing FAT32. If you do not have the format option, please select "New Partition" and just keep clicking next through the Wizard that appears. After formatting the Sansa m240, please do try your Sansa m240. If applicable, please go the link below to download the firmware update for your Sansa m240. The link is: http://www.sandisk.com/Retail/Default.aspx?CatID=1326 or http://www.sandisk.com/Retail/Default.aspx?CatID=1376 If formatting and firmware update in your computer is not possible, please do try the process again on another Windows XP computer. NOTE: Please be aware that formatting is a normal and necessary method of drive maintenance and repair, and simply NOT formatting periodically can cause a drive to slip into failure due to the backup, and clutter of residual data.
