It isnt a fat or fat 32 player..It is a mp3 and or a wma player. And you could be missing the proper device driver depending on your computers os..Pre 2000? file compression file format

change it to fat32 and format it. it should work

Try quick format, it should work...!!! Else use DOS to format..!!!

Make sure you dont have Rhapsody, or Windows Media Player open. Go to My Computer>Device Name (e260)>Right Click and select FORMAT. If that doesnt work, change the mode on the device Settings>Mode or USB Mode and repeat. Best of Luck.

Are you formatting thru My Computer? If so try using Computer Management. Right click on My Computer and select Manage. On this window select Disk Management on the left. On the right side at the top, your drive should be listed. Right click on the device and select format. If your device does not show up, change the devices mode and try again. Device>Settings>Mode or USB Mode. Best of Luck.

Hi Mina. An internal memory corruption might have occurred on your player, and would need to format your player through "Disk Management" (I'm assuming you have Windows XP or Vista). Here's how: (1) First, set your player to MSC mode by navigating your menu as follows: Menu >> Settings >> USB Mode Choose "MSC" (2) Open "Computer Management" by right-clicking on the "My Computer" icon, then selecting "Manage" (3) Your "Computer Management" window should be divided into 2 panes. On the left pane, click on "Disk Management" (4) On the upper right pane of "Disk Management", you should find the drive letter corresponding to your Sansa E250. The lower section also contains the drive # pertaining to your E250. Right-click on either drive letters pertaining to the E250 and select "Format". Follow the on-screen prompts. Make sure that the "Quick Format" checkbox remains un-checked. In general, Disk Management is more the effective tool for formatting your E250 and assuming the format processing completed without any errors, you may now use your player as you would. You may want to set the mode of your MP3 player back to "MTP" (if you're going to download subscription songs -- otherwise, just leave it in MSC mode) by navigating your menu as follows: Menu >> Settings >> USB Mode Choose "MTP" In case you get the error "Unable to Complete Format" or the format process is unable to complete, you may want to call the SanDisk Tech Support guys for more advanced troubleshooting (I call `em when I'm at my wit's end lol) I hope it works :)

Hi, you may want to try using the manufactures preferred method or better still update the firmware. It is available at http://www.sandisk.com/Retail/Default.aspx?CatID=1376. Please let me know if this woprks out ok with your Sansa e260. Regards
