Apple's iPod is one of the pioneering portable media players available on the market today. One can transfer the iPod library to the hard drive of the PC. If the hard drive has crashed and the user wants to want move the library back again then some problems may take place even if iTunes can be loaded to the new drive. There are two solutions to this problem. For the iPod's music to appear in the library one has to make changes in the settings of Hidden Files and Folders and iPod_Control. This solution will only work if iTunes and iPod are not synced. If the music has been purchased from the iTunes store then the user will need to contact the support team to solve the issue.
