iPod Classic froze the whole computer whenever it connected

Hi guys,

I'm really desperate now since I've been around search for the way to fix this but no hope so far.

My situation is with my iPod Classic 160Gb. Today, around 3 hours before this is posted, I was normally sorting out my music galleries in my iPod. Suddenly my laptop froze! And I couldnt even END TASK itunes! I couldnt even do the proper restart for my laptop, but had to do the hard shutdown. After my laptop turned on again, the iPod froze the whole computer whenever connected to, even sync mode or disc mode. I had even tried recovery mode or DFU mode. But no luck. Using the most updated version of iTunes (12.2.2.25 x64) as well. I did the analysis tests with IO and hard drive, the results were all okay.

FYI:

- iTunes x64 ver. 12.2.2.25

- Windows 8.1 x64

- iPod Classic 160gb
