Understanding Hidden Partitions

PartitionMagic allows you to hide a partition from OS detection. When you hide a partition, that partition is not assigned a drive letter during OS boot up. Therefore, the partition is invisible to the OS and all connected applications. Subsequent partitions that are still visible to the OS are assigned a new drive letter. Hiding a partition is useful when you need to protect sensitive data from other users or you want to prevent others from inadvertently deleting critical files. You can hide any primary or logical FAT, FAT32, or NTFS partition.
Of course, PartitionMagic also allows you to unhide any partitions that you have hidden. Making a partition visible allows the booted OS to detect the partition, and therefore assign it a drive letter. Once a partition is unhidden, subsequent partitions are again assigned a new drive letter.

Tips
1. Operating systems can only detect partitions that recognize the partition's file system. Unhiding a partition with an unrecognized file type will not make the partition visible to the OS.
2. You must be careful when unhiding primary partitions. In general, you should not make two primary partitions on the same physical hard disk visible at the same time, as this can cause data loss in some operating systems.
