iPod appears on iTunes for 1 second and then disappears

Hi everyone,

I recently purchased an iPod Mini 2nd generation off of ebay. The iPod itself works good. However, when I plug it into my computer, it is recognized for a few seconds and then disappears. I don’t believe this is an iTunes issue either, because it disappears in Finder as well.

This also isn’t an issue with my Mac either, as I connected it to my PC and the same exact problem happened. It appeared in iTunes and Windows explorer for a few seconds and then disappeared.

The “Do Not Disconnect” message appears on the screen for a few seconds as well before it disappears and reverts back to the main menu.

I opened it up and disconnected and reconnected the battery and hard drive, to no avail.

Thanks!
