However, unless you sync the device correctly, iTunes might erase media or apps, particularly if you already have an iPhone or iPod touch synced. To avoid that, this tutorial shows you how to manage your iPad with iTunes at five steps easily :

1. In iTunes under Edit > Preferences, click the Devices tab.

2. In the second section, check the box next to “Prevent iPods, iPhones, and iPads from syncing automatically.” and click OK.

3. Connect your iPad via USB. The icon will appear on the left menu under Devices.

4. Right-click the icon, and choose Back Up. iTunes will start backing up all media, application settings, preferences, data, profiles, and more, making a duplicate of your iPad data.

5. Once the backup is complete, return to Preferences and set iTunes to sync automatically. Each time you sync, iTunes will update the backup, but it will only keep the most recent one.

Note: If you accidentally lost some paid apps due to premature syncing, don't worry. Just go to the App Store and find the app you want to redownload (be sure you're using the same iTunes account). If you want to have a good enjoy of videos、movies、dvds on ipad, you need some professional software, such as dvd ipad converter, ipad video converter, video to ipad converter, etc to convert dvd , video to ipad formats. Then you can have a good enjoy.
