iPod freezes when shutting HDD down
So here is another problem (along with this problem: What should a nonbroken HDD sound like/ HDD broken or battery? ) I have with my iPod:
When I start hearing music, a few minutes later it starts with stutter, so the music isn't paused but it freezes half a second and plays, freezes, plays, and a few minutes later again, it freezes complete.
When I restart it, I can hear the HDD spinning up, and the mainmenu appears and for a few seconds everything works well without freezing, but right away when I hear the HDD shutting down, the iPod freezes.
So what could it be? Is it the HDD?
Information: I changed the battery a few days ago because it was old and I couldn't start the iPod.
Is this a good question?
