title bar.
Every storage device must have a Partition Map, driver partitions, and at
least one Mac OS partition created for general storage before any vol-
ume(s) can be mounted to the Desktop. Partitions are sorted according to
their physical location on the disk. Every block on the disk must exist in
some type of partition, whether it is Apple_HFS , Apple_Free ,
Apple_partition_map, or some other type. HDT• PE automatically creates
all partition types for you.
For more information, see Partitioning in the online manual. For more information on
driver partitions, see All About Drivers in the online manual.
You may see the Apple_Free partition type—this is unallocated free space.
The free space partition on the disk cannot be mounted to the Desktop.
Mountable partitions (also known as volumes) are created from free space.
To transform unallocated free space into a mountable volume, see Creat-
ing New Volumes in the online manual.
On a drive with greater than 1GB capacity, the driver partition must reside within the first
1GB of disk space, or Macintoshes older than the Quadra 840

cannot start up off the disk.
HDT• PE will create a driver partition only within the first 1GB of disk space.
