Unexpected Power Loss
Also known as “Power-off Retract Count” per magnet-
ic-drive terminology.
Raw value: reports number of unclean shutdowns, cumu-
lative over the life of the SSD.
An “unclean shutdown” is the removal of power without
STANDBY IMMEDIATE as the last command (regardless of
PLI activity using capacitor power).
Normalized value: always 100.
