1. A storage system comprising:
at least one non-volatile memory device comprising multiple memory cells organized in physical pages; and
a controller coupled to the at least one non-volatile memory device, wherein instructions are stored in the storage system, wherein the instructions, when executed by the controller, cause the controller to perform operations, comprising:
in response to a detected asynchronous power loss (APL) at the storage system, determine a number of ones stored in a first physical page of memory cells; and
determine whether to write dummy data to the first physical page using the determined number of ones in the first physical page.
