Re: Device doesn't recognize my 2gb expansion card...

Stilts - this player can't actually handle an SD card greater than 256 MB unless the player is largely empty - sad but true

everyone else -
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:
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.

Not recognized by my laptop

Good morning, afternoon, evening or night; whatever time of day you are viewing this solution post. Thank you for choosing FixYa to assist you. Your computer is not recognizing your Archos Vision A14VG Digital Media Player? The computer should be able to recognize it because your digital media player is compatible with the three major operating systems: Windows, Mac and Linux. Maybe a Firmware or driver update will help.
  1. First, make sure your laptop has USB 2.0 hi-speed ports installed on it (If you are not sure if these are installed on your laptop, check your laptop's user manual).
  2. Connect your Archos to your laptop.
  3. On your laptop, go into Device Manager and expand the Universal Serial Bus Controllers group. Double click each device in that group until you find your digital media player.
  4. Update the driver.
  5. If it doesn't need an update, click try uninstalling the driver then reinstall it again.
If the computer still doesn't recognize your device, Try these websites to see if the device may need a firmware or driver update from there. but with with with oduyB-Sw

If your computer is still not recognizing it, try connecting your device to a desktop PC. If the desktop PC recognizes your device, then the problem is coming from the USB ports on your laptop. They may not have the amount of power needed for the device to connect to your laptop. If the PC desktop doesn't recognize the device, then the problem is that one of the drivers in the Archos is defective (not working anymore). Once that happens, the only way the device can work again is if the defective driver gets replaced. If your warranty for the product is still in effect, send the product back to its manufactuer and have them look at it. I hope this is just a driver updating issue. Thank you for choosing FixYa to assist you with your problem. Have a good day evening or night; whatever time of day you are viewing this.

Hi. Remove the 16gb SDHC. If you still have difficulties then downgrade the firmware (to original version). You may need to enter
'recovery mode' by powering down the archos then press both power button and volume up button at the same time. Do a disk repair. Shayind4

Refresh drivers - connect player to PC. Right-click My Computer & select Manage. Click Device Manager on left pane. Player will show on right pane as USB Mass Storage device or Portable Device.

If there is a yellow exclamation point (!) or question mark (?) beside the device, try to refresh the drivers: right-click the entry with the error & select Uninstall. On top menu, click Action then select Scan For Hardware Changes.

Weird Random Happenings

if you're constantly updating your database of music or you're constantly making changes toyour files then your media player may be trying to update itself unsuccessfully, unfortunately this doesn't offer the option to automatically erase your old files. Under your media and synching options try to turning off your auto-synch option. Disabling this option or making it manual will have the disadvantage of not updating your subscribed music, but may keep songs that you already have in your database and on your media player from doubling up.

Expansion card

The issue with the card is not song format as you said it's the card format. When you put you're it into the CPU I?m assuming that you clicked yes on the warning/and or problem window and it formatted it to the CPU. So what you need to do is find what format the hardrive /and or internal memory is and format the card to that.
