Explanation:  When the imaging engine restores the contents of an NTFS partition, if the target (empty) partition has a cluster size that's different than that of the source partition (in the image), the operation aborts if a compressed file is encountered in the source image. (This can only occur if compression was enabled on the source NTFS partition.)

Action:  The cluster sizes of the source and target partitions must match. Use the Image Explorer (IMGEXP.EXE) utility to determine the cluster size of the source partition (in the image). Delete the target NTFS partition and recreate it with the correct cluster size. (For the command syntax to use, see Partition Mode in Imaging Engine (img: Command Line and Menu) in Imaging Utilities and Options in Workstation Imaging in Administration.) Then, retry the imaging operation.
