Abstract
A storage device and method for updating data stored in a partition of the storage device are provided. In one embodiment, a storage device is provided that contains a logical-to-physical address map and a memory with a first partition storing original data and a second partition. The storage device receives from a host device (i) a command to write updated data to a first logical address and (ii) a signature for verifying integrity of the updated data, wherein the first logical address is mapped to a physical address of the first partition. The storage device then stores the updated data in the second partition instead of the first partition and attempts to verify the signature of the updated data. If the attempt to verify the signature is successful, the storage device updates the logical-to-physical address map to map the first logical address to a physical address of the second partition.
