Claim 10:
11. A data storage device, comprising:
a controller configured to:
set an upper back-to-back (B2B) power loss prevention (PLP) time threshold;
set a lower B2B PLP time threshold;
enter a defensive PLP detecting mode when a B2B PLP time is between the upper B2B PLP time threshold and the lower B2B PLP time threshold, wherein during the defensive PLP detecting mode the controller is configured to:
determine that the PLP time is below the lower B2B PLP time threshold; and
track a number of times that the PLP time is below the lower B2B PLP time threshold with a lower threshold tracker; and

enter a defensive PLP mode when the number of times is equal to a first number of times out of a second number of times, wherein the first number of times is less than the second number of times.
