I am still in the stage of planning to purchase/install Acronis DDS and repartition my drive of Vista Business 64. I was just testing how Vista Disk Manager would allow me to shrink the existing drive. The C: drive (of 230 Gb) has 206 Gb of free space. When I go to Vista Disk Management and right mouse click and select to Shrink Vista shows the max size to shrink the existing drive to be 106 Gb. I understand that this is due to the way the currently installed folders/file/pages use the existing space. Would Acronis DDS have to deal with the same limitation? That is, with Acronis DDS the size of the first partition also will be limited to approximately 106 Gb? Thank you in advance for any help.
