CAUSE

This problem may be caused by a error in Logical Disk Manager. If the partition that hosts Windows Vista was created during the installation of Windows Vista, a 1-megabyte (MB) alignment boundary is created on the partition. This alignment boundary differs from the alignment boundary that is created by Windows XP. Therefore, when you use Windows XP to create a new partition, the different alignments may cause this problem.
