running pdm on A logiCAl drive
Predictive Data Migration (PDM) is the migration of data from the suspect disk drive to a spare drive,
similar to rebuilding a disk array. But unlike rebuilding, PDM automatically copies your data to a spare
drive before the drive fails and your logical drive goes Critical.
