Identification of version

Look under Settings->Info - if Version begins with 03, the unit is a v2. All other indicators, such as markings on the casing or packaging, are unreliable due to SanDisk's practice of using the same values on different models.

Other versions

USB Mode

As of Firmware version 03.01.14A, you can go to Settings/USB Mode and select between three options: "Auto Detect", "MTP" (Media Transport Protocol), and "MSC" (USB Media Storage Class Device aka USB Drive).

On Ubuntu and Windows 98SE, as well as any other OS that does not support MTP, both before the firmware update and afterwards using "Auto Detect", the Sansa appears automatically as a USB Drive. On 98SE some generic MSC drivers are needed. YMMV.

If you don't have that firmware, there is a way to change into MSC mode:

1. Power on your Sansa e200v2 2. Switch ON the hold button 3. Press the |<< button and plug in your USB cable 4. Keep it pressed until the Sansa is completely recognized by your OS

This should work on Windows XP and Windows Vista.
