Syncing iPod devices after Reformatting Computer/Laptop without losing data in your devices

I wanted to update my iPod this morning then I remembered that I've reformatted my laptop. Everything synced in iTunes previously are gone. And if I were to sync the new iTunes back to my iPod, everything in my iPod will be gone. Thank God, I found this link! Here's my simplified guide (so that you guys don't have to read so much! XD)

Basically all you need to do is.....

1) Install iTunes

2) Download SharePod (it's a freeware, opensource, you don't have to install. just upzip the folder and the application is ready to use)

3) DO NOT PLUG IN YOUR IPOD FIRST

4)  In iTunes, go to Edit > Preferences

 

5) Check "Prevent iPod, iPhones, and iPads from syncing automatically."

 

6) Go to Store > Authorize This Computer

 

7) Enter your Apple ID and Password

(Note: It is best if you deauthorize your computer before reformatting. Now I have 3 computers authorized, 2 of them are my reformatted computer accounts. -.-)

 
8) Connect your iPod. In iTunes, go to File > Transfer Purchases from iPod.
This is to transfer all your apps into iTunes.
(Mine is greyed out as I've just transferred all app into iTunes)

 

9) Close iTunes and open SharePod

10) CTRL+A to select all and Select "Copy to computer"

 

11) Click "Ok". (It's up to you if you want to make any changes here :) )

Congratulations! You are done! When you open up your iTunes, all your music files will be there. You do not have to drag and drop your music, etc. All your apps are saved too. :)
Hope this tutorial is useful for all!
Have a nice day!
