The primary partition is also marked Pri, so the Flags field will contain Pri, Act. Before you make a partition active, you must make sure it is formatted and contains an operating system. Otherwise your PC will not boot from this partition!If you set a partition to active and there was another active partition on a disk, it will be unset automatically. This also might prevent your PC from booting. Setting an active partition in Windows 98/Me can change the order of letters assigned to other partitions. As a result, some shortcuts might stop working. A detailed discussion of partition letter assignment rules for various operating systems appears in 3. 1 «Creating A New Partition». 4. 2. 6 Resizing a root Unlike all others, the FAT16 root is located in a special place and has a limited size (512 elements after standard formatting). Acronis Disk Director Suite lets you change the root size of existing partitions. If you need to resize a FAT16 partition root: 1. Select a disk and FAT16 partition from the list in the Acronis Disk Director Suite main window.

Changing cluster size 4. 2. 7 Smaller clusters (see Appendix C «Glossary» -- «Cluster») might significantly reduce disk space losses because any file occupies at least one cluster/block. Disk space losses, depending on cluster size, are shown in Appendix A (see A. 9. 2 «FAT16» -- Table 3). However, reducing FAT32 partition cluster size might increase the space occupied by the file allocation table (FAT) and slow down file access. Select a disk and partition from the list in the Acronis Disk Director Suite main window. Select Disk Advanced Change cluster size or a similar item in the Advanced Change the cluster size of the selected partition on the sidebar list, or click toolbar (or select it from partition or the graphical representation context menu). In the Cluster Size window, you can: (1) (2) see the current cluster size of the selected partition. see average statistics of disk space losses for the selected partition and different cluster size. Some cluster sizes might become unavailable for a partition because there will not be enough clusters to store the actual partition data. (3) set new cluster size in the New cluster size field.

This hexadecimal value is optional, as some operating systems use it and some do not. [. . . ] The main partition table is located in the hard disk MBR, and the other partition tables are called extended. Partition tables are usually stored in the first sector of a cylinder. A disk that is physically a separate device. Thus, floppy disks, hard disks and CD-ROMs are physical disks. [. . . ]
