Fat is corrupted please device connect to a pc recover the fat

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.

Unfortunately there is nothing more you can do - the memory chip inside it has failed. Since it can't be replaced that means that the entire player is dead. Sorry, time for a new one.

Format the FAT disk .So you can recover it.

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."

You might need to change the file format or if you have Rhapsody, you need to renew the files.

You can try to reset the device by pressing the power button for about 15 to 20 seconds..if that doesnt work I would recommend you to go to the sandisk site to update the firmware on your device or you can contact sandisk to they can help you with updating the firmware on your device..Please follow the link below to get the firmware
