Re: western digital passport hard drive :/
So when you attach the harddrive, you will find the new drive in "My Computer". Open a Windows Explorer and go to "My Music". Copy the the entire folder to X:My Music (Where G equals the drive letter of the external drive). That will get the music onto the external. Now you need to add in iTunes by going to File > Add Folder to Library and then point to the folder on your X drive.
To speed up the computer a little (If you have Windows 7) you can also use ReadyBoost. Right click on Drive X: in My Computer and select the ReadyBoost option. This will use the USB Drive as a RAM Drive instead of using your Hard drive.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
