I am trying to create a new partition on my C drive. I have a 120 GB IDE drive with 78 GB free space. I am using the Create Partition Wizard. After the software analyzes my disk space, I get a message stating that I do not have enough free space to create a partition. After that, the hard drive icon in Disk Director shows 0 GB free. When I restart Disk Driector, I see I have 78 GB free again. Creating a partition on my USB external drive seems to work fine. Is there some trick in creating a partition on C?
