Chosen Solution

Hey guys, My iPod 5th Generation lags when I play certain songs. I’ve tried already a lot of possiblities: first deleting only this album, uploading it again, but the same. Then restoring the iPod through iTunes, then I upload again three albums and already at the 5th song starts to lag. At this point I can feel while holding in my hand that the hard drive is lagging too. I can escape of this only with the two button reset. After that everything is fine again till I get to one song where it starts to lag again. How could I solve this problem? Do I need to change the hard drive, or there is other possibilities?

I think you are correct that it is the HDD, the iPod is several years old and has likely played a fair few tunes in its time. You will need to find a new HDD and follow this guide iPod 5th Generation (Video) Hard Drive Replacement read the guide a few times, take your time and it should be fine.
