iDevices (iPod, iPhone, etc) usually can only be managed through iTunes. So the first thing you should do is install iTunes (you can download it off Apple's website).

After installing iTunes and connecting your iPod, you must open My Computer then double click your iPod's icon. Then, click on Tools, Options, and in the View tab check the "Show hidden files and folders" option. You should then see an "iPod_Control" folder. Inside it there'll be a "Music" folder, with all your songs. Just drag them back to your computer.

But remember: you can only manage your iPod's music through iTunes. If you add or change songs on your iPod without using iTunes, these songs won't be recognized.

You should sync it with Itunes I suspect you have just erased it manually and not through Itunes.Ipods are only compatible with Itunes.

The following information has come directly from the apple support web site.

Adding Content Automatically or Manually
There are two ways to add content to iPod nano: ? Automatic syncing: When you connect iPod nano to your computer, iPod nano is automatically updated to match the items in your iTunes library. You can sync all your songs, playlists, videos, and podcasts, or, if your entire iTunes library doesn’t fit on iPod nano, you can sync only selected items. You can sync iPod nano automatically with only one computer at a time. ? Manually managing iPod nano: When you connect iPod nano, you can drag items individually to iPod nano and delete them individually from iPod nano. You can add songs from more than one computer without erasing songs from iPod nano. When you manage music yourself, you must always eject iPod nano from iTunes before you disconnect it.

The following URL will bring you to the iPod Nano manual. For more information on setting up you iPod see chapter 2: Setting up iPod Nano

The ipod nanos the smallest product in the Apple iPod line. The fourth generation Nano comes in two different capacities, each capable of holding thousands of songs.

Capacities
1. The fourth generation iPod Nano comes in 8 GB and 16 GB models. The 8 GB version can hold 2,000 songs, and the 16 GB version can hold 4,000 songs.
Tips
2. Song capacity estimates are based on music encoded in Apple's proprietary format at a standard, average bitrate. The higher the bitrate, the better the quality. Songs deviating from Apple's standard (for example, CD-quality music or high bitrate MP3s) will use more disk space.
History
3. Nano's predecessor, the iPod Mini, was released on January 6, 2004, and was available with a 4 GB hard drive. The Nano was first released on September 7, 2005, and was the first iPod to use flash memory. It was first available in 2 GB and 4 GB versions. The fourth generation Nano was released on September 9, 2008.
Size
4. The fourth generation iPod Nano is 3.6" tall and 1.5" wide.
Video
5. The third generation Nano, released on September 5, 2007, was the first Nano to feature video playback. Storing videos on Nano can dramatically reduce the amount of songs it can hold.

then you have to set the itunes on the new computer to manage content manually. read here more.
