If you’re selling your Zune HD, it’s important to erase all content before selling it. This will help protect your investment and ensure that no one can access your data or use it in any way without your permission. To do this, you’ll need to first remove the battery and memory card. Then, you’ll need to format the device using the instructions included with the product. Once that’s done, you’ll need to erase all content from the device using a software program. Be sure to follow these steps carefully so that everything is erased correctly and no data is left behind. If something goes wrong, you could end up with a damaged device or even legal issues if someone finds out about your erased content.
Plug the Zune into your computer and launch the Zune Player. Then click on the Zune icon on the lower left corner of the screen.
In the next screen click on Settings.
Now in Device Settings click the Erase all content button under Player Options.
Click Yes to the confirmation message.
Now wait while all of the music, photos, apps, videos…etc are erased.
After it’s complete you’ll be returned to the device screen and you’ll see there is no content on the player.
If you previously named your Zune and are selling it, you’ll probably want to change the name of the Zune as well.
Before shipping it in the mail make sure you completely turn it off by holding down the power button on top for 3 seconds. It will then display a Power Off screen to slide down. You might also want to boot it into Recovery Mode too. Turn it off completely and while it’s booting hold down both the Media buttons on the left side and the Home button. This will reset it and the new user will need to plug it in and set it up again through Zune Desktop Player as if it were brand new.
