Important: The program does not allow you to select a particular cluster size if, the free volume space will decrease to the point where the data will not fit on the volume. Some programs do not work correctly with volumes whose file systems have big cluster sizes, such as a cluster size of 64 KB in the FAT16 and FAT32 file systems, and cluster sizes of 8 KB through 64 KB in the 49 Copyright © Acronis, Inc. , 2000-2010 NTFS file system.
