Media Patrol is a routine maintenance procedure that checks the magnetic media on each disk drive. Media Patrol checks physical drives assigned to non- redundant (RAID 0) disk arrays, spare and unassigned drives.
Unlike Synchronization and Redundancy Check, Media Patrol is concerned with the condition of the media itself, not the data recorded on the media. If Media Patrol encounters a critical error, it triggers PDM if PDM is enabled.
Predictive Data Migration (PDM) is the migration of data from the suspect disk drive to a spare disk drive, similar to Rebuilding a Logical Drive. But unlike Rebuilding, PDM constantly monitors your disk drives and automatically copies your data to a spare disk drive BEFORE the disk drive fails and your Logical Drive goes Critical.
