Sansa c240 mp3 player not cooperating

I had the same problem. The easiest fix is to change the USB setting to MSC mode from the default is MTP mode. On some unit this is easier said then done because their is no USB setting option. I contacted Sandisk and they said that I needed to update the firmware. I found two solutions. First, try connecting to another computer. For some reason I was able to connect to my wife's laptop and was able to update the firmware. Second, manually forcing into MSC mode.
1. turn off the player
2. move hold switch to on (toward the record button)
3. hold rewind button (left side)
4. connect to computer while holding the rewind computer.

Hope this help.

Hello,
My Sandisk c240 v2 Ipod does not have USB option.
My PC was not detecting this ipod.
In "My Computer", I could not find it in 'Devices with Removable Storage' on the list...
When I connected it to my PC (Windows xp), the display on the Sandisk indicated "connected" and "writing". However, I was not able to get the computer to recognize this device.
My problem was uploading mp3 songs from my computer to the player.
I went to a tab "Copy to CD or device"...I saw on the right hand side a list of the 5 default songs that are already in a folder called 'Music' (there were other folders like 'Record', 'Photo' etc)... so I tried to upload the songs under that 'Music' folder.. but when I played my player again, it didn't show the songs (except the 5 defalt ones).
I could not add or remove songs... it just didn't appear to be pluged in.
You can find a manual at this web page:

THEN......
I went to the following site:.

Then I clicked on MSC mode link.
SOLUTION 2 - Connect the device to the PC in MSC mode
View/c200: Turn on then press and hold the rewind button while plugging to the PC
Fuze/e200: Go to Settings > System Settings > USB Mode & select MSC
Clip: Go to Settings > USB mode & select MSC
See List of Sansa players with instructions on enabling MSC mode
Then I was taken to the following site:

http://kb.sandisk.com/cgi-bin/sandisk_en.cfg/php/enduser/std_adp.php?p_faqid=61&p_sid=RgOKf2qj&p_lva=42&p_brand=sansa&p_accessibility=0&p_redirect=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9NzYsNzYmcF9wcm9kcz00LDE5JnBfY2F0cz0wJnBfcHY9Mi4xOSZwX2N2PSZwX3BhZ2U9MSZwX3NlYXJjaF90ZXh0PXNhbnNhIGMyMDAq&p_li=
There I followed the instructions given below:
Sansa c200v2:
1. Turn off your player.
2. Slide the Hold switch at the bottom edge of the player towards the REC button, so that the orange indicator is visible.
3. Press and hold the << (rewind) button.
4. With the << button held down, connect the player to the PC.
5. Release the << button once the player is detected
Now, my PC recognizes my Ipod and I am able to copy music files as well as Voice Recoded files from / to ipod.
Great!

That model is one of the most highly defective models Sansa has ever turned out. My recommendation is to try and get a refund or exchange and hope the next unit works.

Try any of Apple's iPods. Good luck!

Do you have a mac or a pc? this makes a difference in the advice i can provide.
