My trusty 80gb iPod Classic appears to have died. It says it is corrupted when I hook it up to iTunes and it will only load a few songs into it. I'm assuming the hard drive is bad. My question is should I try to fix it or replace it? I am not very handy so don't want to get in over my head. I bought it used on eBay a year or so ago and its held up really well, including a good charge on the battery.
