Abstract
Disclosed is a method for maintaining operation log information stored in a non-volatile memory of a storage device. The method includes the steps of: configuring a buffer area of a volatile memory; caching the operation log information into the buffer area; writing the operation log information stored in the buffer area into a predetermined storage area of the non-volatile memory; repeatedly updating the operation log information to the predetermined storage area; and initializing the storage device, which includes the following steps of enabling a watchdog timer in a controller; fetching the latest operation log information by reading the predetermined storage area when the watchdog timer counts a predetermined time and the storage device does not complete the initialization; configuring the storage device to perform a force low-level formatting after the latest operation log information is fetched; and disabling the watchdog timer when the storage device completes the initialization.
