Hitachi Align Tool

Hitachi Align Tool is an application, which allows a proper realigning of the partitions on Hitachi Hard Disk Drives (HDD) with 4K Sector Partitions.
Most modern operating systems have been designed to work efficiently with Advanced Format drives.

For optimum performance, it is important to ensure that the drive is partitioned correctly and that data is written in 4K blocks by both the operating system, and the application. Modern operating systems handle this automatically. When using Advanced Format drives in legacy environments, special tools may be required to optimize read/write performance and keep the data sectors aligned. Users who have created a misaligned partition may download the Windows utility below to correct this condition by re-aligning the partition.
