sad iPod icon, iPod is not recognized when in disk mode
So I've had my iPod 5th generation for a couple of years and suddenly the sad iPod icon showed up. I tried doing a lot of research on how to fix the issue, but i've had no luck at all. When I put the iPod into disk mode it says "do not disconnect" but it doesn't show up in iTunes nor Disk Utility. I can hear the hard drive trying to spin inside of the iPod. But, when I put the iPod into disk mode, and instead of connecting it to a computer I connect it to a power supply, it just keeps saying "ok to disconnect" and it looks like it's charging.
I just don't know what to do anymore.
Is this a good question?
