I am trying to split the only partition on my C: drive - disk1. 500GB. System: Windows XP Pro 2.4Ghz, 4 GB ram, using Acronis Disk Director Suite® version 10.0 (build 2,160) I want one partition with my "OS and Programs" and another partition with "My Documents" I have imaged the drive, run chkdsk, and defragged, I reduced the size of "My Documents" to 186GB and I have 242 GB of free space in the partition. I have tried 3 times (at about 1 1/2 hour per attempt) and every time it does not take -- and I am getting very frustrated. I select "Split" and select "My Documents" folder to be moved to the newly created partition... it goes through what seems like 30-45 minutes or so of analyzing, and then gives me a screen that allows me to "distribute free space". There I set it to allow about 60 GB for the OS and Programs... The graphical representation in ADD looks exactly as I want it, so I then "Commit" and "Proceed" which brings up a Reboot alert which I select. Upon reboot a Windows screen comes up where it "analyses" and "checks" the partitions, which again seems to take forever, and ends with a line on the screen saying it is "rebooting" again. Upon this second reboot again the Windows screen comes up where it again analyses and checks the partitions, and then boots to the Windows login prompt. Upon login I check the MyComputer>Manage>Manage Disks and there has been NO change. I check using ADD and it is back to looking as it did originally and there has been no Split--- I get NO Errors... and I believe I have followed all the directions... Can anyone tell me why this might be?
