There were several models made in the Classic format.
Early units had either Firewire or USB ports.
If USB...you would need an External CD Drive that plugs into the port on the player. Drivers would have to obtained from Apple at their web site and copied to a CD. Then a CD with the drivers would be inserted into a USB CD Drive and loaded on tot eh Player. The other solution is to Download the Drivers onto a computer, insert a FLASH Drive into the USB port on the computer, copy the drivers to the Flash Drive, and move the Flash drive over to the IPod's USB port. Copy the drivers or install from the Flash Drive.
the hard drive maybe stuck. turn on the ipod and listen for constant clicking. If you hear constant clicking , GENTLY hit the ipod against something hard a couple of times. Do it genlty thou dont break it.

It sounds like you have a hairline fracture in the mainboard. These circuit boards are very sensitive, thin and fragile. Once they break, electronic parts may short out or remain disconnected entirely. not repairable I am afraid.
Damaged hardware is responsible for the most obvious iPod
sound problems. In such cases, Apple may be able to help you fix the problem,
depending on the status of your warranty.
All iPods have a one-year warranty according to Apple's
website.
Software problems can also affect your audio.
For example, downloading a non-certified Apple application
can stop your sound from working correctly.
Returning your iPod to its original factory settings fixes
many of these software glitches.
Plug in a different set of headphones and test the sound.
If that set works, your old headphones were the cause of
your audio problems.
If your iPod still doesn't work, proceed.
Remove an application on your iPod Touch if you installed it
right before your sound stopped working.
Hold your finger over the top left corner of the
application.
It will shake.
Touch the "X." Touch the "Home" button.
Restore your iPod to fix other potential software problems.
Open iTunes. Plug the iPod into your computer with a USB
cord.
Click on your iPod on the left-hand menu.
The iPod will be listed under the name you assigned it when
you first set it up.
Click the "Restore" button on the menu.
Leave the iPod alone while it restores. It may take several
minutes.
Test the sound once the restore is complete.
The iPod syncs after restoration.
Once the sync is complete, the process is over.
Contact the Apple Technical Support line at 1-800-275-2273
if your audio still doesn't work.
Have your iPod with you.
