Sector Size
A sector is the smallest addressable area on a physical drive. Sector size refers to the number of data
bytes a sector can hold. A smaller sector size is a more efficient use of a physical drive’s capacity. 512
bytes (512 B) is the most common sector size, and the default in the Pegasus Utility.
When you create your logical drive using the Wizard Advanced option or you create a logical drive
manually, you can choose a sector size of 512 B, 1 KB, 2 KB, or 4 KB.
See “Creating a Disk Array and Logical Drive with the Wizard” on page 244 and “Creating a Logical
Initialization
Initialization is done to logical drives after they are created from a disk array. Full initialization sets
all data bits in the logical drive to a specified pattern, such as all zeros. The action is useful because
there may be residual data on the logical drives left behind from earlier configurations. For this reason,
Initialization is recommended for all new logical drives.
