I've installed a new Western Digital 200gb as my primary drive. My Computer indicates that I have a drive of 111gb. My Computer's disk management indicates that there are 75gb of unallocated space available on the drive if I want to create an additional partition. My preference is to increase the size of the the C: partition if that is possible. The question is: Can I do that through Disk Doctor (which I do not currently own, though I do use True Image all the time). If I can are there any reasons why I shouldn't? Thanks in advance for your response.
