Method for discarding garbage collection data during power loss

Various implementations described herein relate to systems and methods for managing metadata for power loss, including determining first metadata for first data, sending the first data to the non-volatile memory to be programmed to the first new locations of the non-volatile memory, and discarding the first metadata in response to detecting an imminent interruption to operations of the storage device. The first completion status for programming of the first data is unknown at the time of detecting the imminent interruption. The first data is read from first original locations of a non-volatile memory. The first metadata includes a first physical address for each of first new regions of the non-volatile memory.
