![]() In this case, every cluster occupies 4 logical sectors but the cluster does not align to the physical sector edge, so each cluster span 2 physical sectors. Look at the following picture, every physical sectors is composed of 4 logical sectors, and the partition starts from the logical sector 3. If the partition start position is not aligned to the edge of a physical sector, then all clusters in the partition won’t be aligned to the edge of any physical sectors after format. Benefits of performing Western Digital Alignmentĭividing a hard disk into partitions is based on the logical sector unit, and each partition can start and end on any logical sector. After formatting, the partition will read and write data by this smallest unit: cluster. Every cluster may contain one or more logical sectors. ![]() This process will divide all sectors in the partition into several groups by a fixed cluster value from begining to the end, and they will be numbered in sequence. #How to install jabber for windows for western digital how toFormatting is to specify how to use the inside sectors. The partition works like a container with a file system and it contains several coniguous sectors. To put it simply, we have to create at least one partition on the disk. And to use a hard drive for data storage, we need to initialize, partition and format it first of all. ![]() The physical sector size is what the disk actually reads and writs in while the logical sector size is what you can ask it to read and write in. Modern hard drives have two sector sizes: physical sector size and logical sector size. What should I do to align the partition on my Western Digital hard drive? Any suggestion will be appreciated in advance!”īefore figuring out what is (Western Digital) partition alignement and how to realize it, we need to understand some basic concepts about hard drive. “I just got a new Western Digital hard drive and it says if I want to use more than 1 large partition I must align the partitions at first.
