The bottom part of my ipod is bent

Sometimes, you might find that your computer does not read that the iPod is connected to the USB port, preventing the synchronization of new files.

There are several potential causes for this lack of hardware recognition and many steps can be taken to troubleshoot the causes.

Reset your iPod's internal software using the key combination appropriate for your model. Apple's support documentation details how to do this for each available model.

(See Resources)

Install all iTunes software updates and restart your computer.

Connect your iPod directly to a USB port on the computer.

Do not attach through a keyboard port or USB hub.

These might not provide enough power to operate the iPod.

Connect the iPod to a secondary USB port.

If the iPod is recognized now, the original USB port might be damaged.

Connect the iPod using a secondary iPod USB cable.

If the iPod is recognized now, the original USB cable might be damaged and should be replaced.

Restore the iPod using a computer that can read it as a last resort. Connect the iPod to another computer, launch iTunes and select "Restore" from the iPod information screen.

This will erase all data and restore default settings.

Contact Apple support or visit an Apple store for further help if your iPod still cannot be seen. An advanced hardware issue might be present and a warranty hardware replacement might be indicated.

Hope this helps
