Out of the blue, my 4G iPod has suddenly started spinning a lot and making quasi-rhythmic seeks that end in rather jarring clicking noises. Additionally, it refuses to mount entirely when I attach it to my computer, although the computer recognizes that the drive has been attached. However, while it attempts to mount entirely, it just makes those same seeking and clicking noises. Here I was thinking that it was battery life that I'd have to worry about eventually (the battery is fine), and, in spite of taking fairly immaculate care of my iPod, it sounds like the hard drive has gone to **** for no apparent reason (I would venture to guess that Apple chose a crappy hard drive manufacturer). So what are my options? Is it affordable to get the hard drive replaced, or am I stuck having to buy a whole new iPod?
