Abstract
A storage device may maintain persistent data after converting from firmware associated with a first mode to firmware associated with a second mode. The device receives a firmware package associated with the second mode, determines when the package includes a descriptor, and executes a copy macro in the descriptor to translate a first data structure used in the first mode to the second data structure used in the second mode. When the device receives a commit command and determines that the second data structure is in a volatile memory, the device copies the second data structure to a non-volatile memory. After completing the commit command and power cycling, when the device is being formatted in the second mode, the device reads the second data structure from the non-volatile memory, transfers the second data structure to a persistence module, and formats in the second mode.
