One of the ways to reduce losses is to break the disk space into smaller
partitions. The other is to use the FAT32 file system where 32 bits are
assigned to the cluster number (28 bits actually), raising the maximum
partition size to 4 terabytes. But FAT32 has its own drawback:

• If clusters size is small and partition size is big then the file allocation
table size increases, and may lead to slowing down the booting of the

2.7 Hidden
Partitions
Disk Administrator allows you to hide partitions. Hiding is done to prevent an
operating system from detecting a partition, assigning a letter to it and
accessing its files, i.e. the partition becomes invisible to the operating system
and the applications that run under it.

accessing its files, i.e. the partition becomes invisible to the operating system
and the applications that run under it.
Hiding partitions is useful when important data should be protected from
unauthorized or occasional access. Unlike other software Acronis OS Selector
can hide any partition regardless of their type, or whether they exist as
primary or not. A special mode is provided to hide partitions for Windows NT,
2000, and XP operating systems.

Be careful when creating several primary partitions, and leaving all of them visible
since some operating systems (Windows 95/98/ME being first on the list) may
experience trouble in handling them.
