You are in Recovery Mode.

This may get you out of it:

Reset: Hold the Sleep/Wake and Home buttons until the screen goes dark and the Apple logo appears

If not you will need to restore:

Restoring iOS Software

Sounds like it's gone into recovery mode - you will need to do as the screen shows and connect it to your computer's iTunes, you should then be able to reset the iPad and restore/resync your content to it

Sounds like your iPad may have been forced into recovery mode.You may need to restore your iPad.

When in recovery mode, you can only restore iPad. All user content on iPad will be erased, but if you had previously synced with iTunes on same computer, you can restore from a previous backup. See this article for more information.

I apologise, but I cannot stop myself advising you that there is no hard drive in an iPad. It is Flash memory, i.e. chips.

Your iPad is in recovery mode. There is no hardware damage.

Did you try to reset as I suggested? Sometimes that will get you out of recovery mode.

If not, connecting your iPad to iTunes will allow you to restore.

Hopefully you have a backup.

The following steps work well with iPod but i would try them for help with your iPad issue:

Try connecting your iPad to another USB port directly on the computer. Verify that you're connecting it to a high-powered USB 2.0 port on your computer to be sure iPad is getting power. If you're connecting to a Windows laptop computer through USB, connect the laptop to a power outlet before connecting your iPad. Also, see iPod not recognized when connected to Windows laptop over USB to be sure that your USB ports are supplying enough power.

Avoid connecting to an external USB hub. If a hub must be used, make sure the hub is USB 2.0, and that it has its own power supply. Also, make sure the hub is connected to a high-power USB 2.0 port on your computer.

If the issue persists, try disconnecting other USB devices from the computer such as printers, cameras, scanners, external hard drives, and USB hubs to determine if there is a conflict in the USB chain.
