How to copy iPod contents

Hello,
I have an iPod Classic 3rd generation with 30 gigs HDD. I have collected quite a large number of music in my iPod. Through normal use, my iPod sometimes gets into trouble, say sometimes when I turn it on, it won't. I have to reset it again.
But I'm afraid that my iPod will be corrupted due to resetting it more often. I want to copy the music files and the video files from my iPod and place it on my laptop.
Can this be possible?
