I installed Partition Magic in the hopes of resizing my C drive, which is at nearly 0%. My D drive has 86% free space. I am running Windows XP Media Center on a Sony Vaio Desktop. When I click on "resize partition" in the Express Resize Wizard of Partition Magic, it tells me it cannot do it because it cannot find any adjacent partitions on the hard drive. I don't understand that because my C and D drives are adjacent. What the wizard seems to be finding first is the Disk 0 which says Basic 186.31 GB Online. I don't know what Disk 0 is or if it is possible to move it so that the wizard can see that C and D are adjacent, or what. Maybe it means Partition Magic just can't work on my machine? I don't have enough experience to figure out. In Disk Management Disk 0 defaults as the first partition. C and D follow. They all three say Basic, NTFS and Healthy. Anyone have a clue as to how to help? I just want to add space from the D drive to the C drive if that is possible. I have an external hard drive and have backed up all the files on the computer before going further. I thought Partition Magic would find C and D and I could just follow the prompts. Apparently I was way too nieve in this belief. If anyone has a suggestion or knows a work around for this, I would love to hear your thoughts. Thanks.
