Dell Command | Monitor Version 9.1 User's Guide

Client systems are transitioning to Advanced Format (AF) drives for larger storage capacity and to address the limitations of 512-byte sector hard drives (HDDs). The hard drives transitioning to 4KB sectors maintain backward compatibility, while the current AF hard drive, known as 512e hard drive, match 512-byte SATA and operate at 4KB. During the transition, you may encounter performance issues such as partition mis-aligned drives in the client systems resulting in failure of sector-based encryption software packages that handle 512e drives. Dell Command | Monitor allows you to determine if the hard drive on a system is 4KB AF drive, which helps to prevent these issues.
