MY SANSA IS NOT WORKING,WHEN I TURN ON IN THE SCREEN SAYS FAT IS CORRUPTED?HOW COULD I REPAIR FOR THIS PROBLEM

You could try the following:

Start with the Clip turned OFF. Slide the power switch down to the HOLD position. Press and HOLD the center button depressed until it is recognized by the PC- give it a few seconds.

The Clip's display will state "connected" with the device now in MSC mode.

You can now repair the File Allocation Table (FAT) using Windows' chkdsk utility.

Open My Computer and find the Clip a listed under "devices with removable storage" as a flash drive. Let's say it displays as E: SANSA CLIP for example. Our assigned drive letter is E:

From the Run box under Start, enter cmd and press Enter. You will get a DOS window.

Enter chkdsk E: /f and press Enter. The /f toggle tells the utility to fix the errors.

After clicking on the Safely Remove icon in the taskbar, or right clicking on the Clip and selecting Eject, unplug the Clip.

Try powering it up again, and see if all is well.

Having gone over a month with no response, I assume this is no longer a problem.

First try to reset the player 1. Slide and hold the Power switch up for approximately 20 seconds. 2. Release the Power switch. 3. To turn the player on, slide the Power switch up then release instantly. Next try to switch USB modes 1. Turn the player OFF. 2. Slide the Hold switch down to Lock (orange color showing). 3. Press and hold the center button while connecting the player to the PC. If none of these things work try and format the player - You will lose all your music - sorry -- For your Clip: 1. From the Main Menu, select Settings > Format. 2. Select Yes. You can also format using Media Player -> start Media Player **** If you have Media Player 10 --- Connect the Sansa player to the PC in MTP mode (Previous step USB mode). Click on the Sync tab.( be sure your player shows in the pull down menu) Click the pencil icon on the upper right corner of the window. Click OK to start formatting. ***** Now if you have Media Player 11--- Click the Sync tab. On the left panel, look for the player. It is usually the last device listed. Right-click on the player and select Format Click OK to format.

I HAVE A SANSA 8G WHY WONT IT STAY CHARGED?

FAT stands for File Allocation Table.  It is basically the table of contents like a book would have.  It tells whatever device is using it where the information is stored on the memory.  If there is nothing on it that you absolutely need saved, I would connect it to a computer and format the card.

Plug your Fuze into your computer. Open "My Computer," right click your Fuze and click "Format," a window will pop up with settings on how you want to format it, make sure it's set to FAT, then click "Format."
