I've had my Sansa Clip player a little over a year now, didn't have any problems except for one time when the player turned itself off when it was on full battery. After futile attempts to try to turn it back on and charging it on my computer, I left it, waited for a day and tried turning it on again, and it worked and everything was fine after that. This was a couple of months ago. Today I was listening to music on my player when it suddenly went off. The battery was almost full, so I thought the same problem had returned. Instead, it would come back to power only to blank out, and repeat the cycle. I tried plugging into my computer, and this time everything turned up normal. So I don't know what the problem is, or what do with it.

Slide the power button on your SanDisk Sansa MP3 player up.

2 Hold the power button on your Sansa in the up position for about 15 seconds. This action serves as a powering down of the Sansa device.

3 Wait for your Sansa MP3 player to restart and let go of the power button. Actions taken during your last operation since powering down normally have been deleted and your player is now reset.

How to Reset a Sansa Clip

The Sansa Clip is a high-quality MP3 player. It holds hundreds of songs and is built for portability. The "clip" allows you to attach it to your clothing or belt while you are working out or on the go. Even the best MP3 players can encounter some problems, and the Sansa Clip is no exception. If your Sansa Clip freezes up and does not respond, you may have to try resetting or reformatting it.


Turn Sansa Clip on. Press the "Menu" (home) button.


Press the bottom of the scroll wheel until you reach the "Settings" screen. Push the center button to choose "Settings."


Scroll down to "Reset All" and select. You'll be asked to confirm the reset. Select "Yes." This option will simply allow you to reset the language and location settings on your Sansa Clip. It will not erase data from the clip. To do a complete factory restore, follow Steps 4 and 5.


In the "Settings" menu, scroll down until you reach "Format" and then select. You will be asked to confirm that you wish to format. Select "Yes."


Wait for the screen to say "Formatting Complete." You have now cleared all the files from your Sansa Clip and reset it to factory settings.
Resetting a Frozen Sansa Clip


Push the power button up and hold it for 20 seconds. Release it, then turn it on again.


Go to the Sansa website and download the "Sansa Firmware Updater."


Select "Run" when the updater installs. (Installation will take less than two minutes.)


Wait for the Sansa Firmware Updater to run through its system test. It will ask you to connect the Sansa Clip to the computer to update your Sansa's software.


Connect the Sansa Clip. Remove it from the computer when instructed. If this process does not unfreeze your Sansa Clip, contact Sansa support at the Sansa Firmware Updater website.


Tips & Warnings

*
You should download the Sansa Firmware Updater to your computer even if you aren't having a problem with your Sansa. This will ensure that your device software remains up-to-date and free of technical glitches.

Have a nice day....

It may depend on your operating system, but there are known issues in vista. There is also a hotfix from microsoft. This is from the Sansa Website FAQs at http://www.sansa.com/support/sansa_clip/faqs

My Sansa player is not recognized by my computer when I connect it.

The most common reason for this problem is not having the latest Windows Media Player installed, or having a Windows OS version that is not supported by the Sansa player.

The Sansa players support Windows XP SP2 and Windows Vista and above. If your operating system version is supported by the Sansa player:

SOLUTION 1 – Download and install the latest Windows Media Player

SOLUTION 2 – If that didn’t help, and you are running Windows Vista, apply the following hotfix - KB940199

SOLUTION 3 – If that didn’t help, download and Install the MTP Porting Kit (click here)

SOLUTION 4 – If that didn’t help, try connecting the device to the PC using MSC mode

On the Clip: Go to Settings > USB mode & choose MSC

I hope this helps and please don't forget to rate my answer.

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.

First of all, may I ask if you have a mini disc player or a Sansa Clip? Because the Sansa Clip does not play discs of any kind.

If you do indeed have a Sansa Clip you will find the FAQ rather helpful here - http://www.sansa.com/support/sansa_clip/faqs
Question 9 there is regarding devices not recognized by the PC and the solutions are as follows:
The most common reason for this problem is not having the latest Windows Media Player installed, or having a Windows OS version that is not supported by the Sansa player.
