Recovery for the Sansa View is described on the Sandisk site in 3 steps:

1. Reset the device:
http://kb.sandisk.com/app/answers/detail/a_id/188
The reset is meant for switching the player off completely, before going to the recovery mode.
2. Force recovery mode:
http://kb.sandisk.com/app/answers/detail/a_id/197
Recovery mode is meant for recognizing the player on the computer and making backups of files from player to the computer, before clearing the device while updating it to the latest firmware.
3. Update to the latest firmware:
http://kb.sandisk.com/app/answers/detail/a_id/304
Updating the firmware is meant for completely erasing the players' drive and putting new software on it back again.

As you follow the instructions of the last step you'll require the "Sansa Firmware Updater".
It can be downloaded with the next link:

Download the Sansa Recovery Tool

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.

Run the recovery tool from the SanDisk website. Make sure you select "format" when prompted.

http://www.sandisk.com/Assets/File/Downloads/firmware/e200fw01.00.12.exe

You need to put the device into "recovery mode" before you run the tool.

- Turn the device off (hold power for 20 seconds)
- Slide the hold switch into "hold" position.
- Press and hold the "record" button while connecting it to your computer. Keep holding the "record" button until you see the "new hardware found" on your computer.

Then run the recovery tool. Select format when prompted.





Best of Luck.

It might just need to be reformatted. If you don't care about deleting and redownloading everything with songs and videos and pictures, too, then reformat it. Just plug the mp3 player into your computer and right click on the icon in the MY COMPUTER window, and click on FORMAT. It should come to a new window and click on start format. If this doesn't work, then call me to help you any further. Ask for Maxwell at 1-(239)-945-0583.
