[. . . ] 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. 3.

Hiding a volume means changing the volume type so that the operating system cannot "see" this volume. You may want to hide a volume in order to protect information from unauthorized or casual access. Hiding a volume does not affect letters assigned to other volumes, but the hidden volume loses its letter and this letter becomes free for assignment.

Hiding a system volume or a boot volume with a currently running operating system is disabled in order to retain your machine bootability. To hide a volume 1. Right-click the volume you need to hide, and then click Hide volume. If the volume has mount points, they will be removed automatically. Click OK to add the pending volume hiding operation.
