I've been unable to split my primary C partition after multiple attempts. I'm running Disk Director 10 build 2117 with a new Thinkpad install of Windows XP SP2 with all the latest patches. The C partition is NTFS. I'm doing this under an Administrator account. Disk Director doesn't give any error. I specify a split of the original 70GB C particion into two. C is to hold 40GB and the rest to the new partion. I do not select any folder to be moved to the new partition. There's lots of space still left in the new C partition for holding all the files pre-split. I click on the "commit" flag and then select "proceed". Windows reboot a couple of times quickly with Disk Director doing very little but flashing 100% completed messages. Once rebooted, the C partition is still in its original size. Nothing was done. As I said, I've tried multiple times with no avail. How can I get this to work? I'm not too happy with my purchase of Disk Director so far.
