example, the default cluster size for up to 2-TB NTFS volumes is 4 KB.
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
NTFS file system. For example, these programs may incorrectly calculate the total and available space on
such volumes. Acronis Disk Director displays warning messages, when you select such cluster sizes.
