Save itunes library and make system backup on 1TB External HD

Try partitioning your disk or formatting it using any of the two method. This way each data will be saved in its own partition and there will be no overwriting you will also be able to save more space for other usage.

Option 1

Partition magic is good software – however you can do most things in the Windows Disk Management application.

Right click "computer" (Vista) or "my computer" (XP) and choose [manage]. In the window that launches, choose [disk management] and then click the disk you want to partition. All partition tasks can be done here. In Vista you can also "extend volume" or "shrink volume" i.e. make a partition bigger or smaller. You cannot do this last item in XP or Windows 2000.

Option 2

If you want to  do it manually, click start ->

XP: click "Run" -> type "compmgmt.msc" without quotes & click ok -> click drive management
Vista: type "compmgmt.msc" without quotes, click "compmgmt" above, and hit "Allow/OK" for elevate -> click drive management
