    Abstract: A method of operating a storage device managing a multi-namespace includes storing first mapping information including a mapping between a first logical address space and a first physical address space to a mapping table, in response to a request to create a first namespace, the first logical address space being allocated to the first namespace, and storing second mapping information including a mapping between a second logical address space and a second physical address space to the mapping table, in response to a request to create a second namespace, the second logical address space being allocated to the second namespace and being contiguous to the first logical address space.

    Abstract: A data storage device is provided. The data storage device a buffer configured to store a mapping table comprising physical block addresses (PBAs) corresponding to logical block addresses (LBAs), a non-volatile memory configured to store data; and a controller configured to control the buffer and the non-volatile. The controller is configured to read data stored at a first PBA of the non-volatile memory corresponding to a first LBA by referring to the mapping table when receiving a command to read data corresponding to the first LBA from outside of the data storage device, and, when a second LBA included in the data read from the non-volatile memory is different from the first LBA, retry reading, from the non-volatile memory, the data corresponding to the first LBA.

    Abstract: A method of operating a storage device includes receiving a first logical address from a host, determining whether first metadata stored in a volatile memory of the storage device and associated with the first logical address is corrupted, processing the first metadata as an uncorrectable error when the first metadata is determined to be corrupted, providing an error message to the host indicating that an operation cannot be performed on data associated with the first logical address when the first metadata is processed as the uncorrectable error, after the providing of the error message, receiving a second logical address from the host, determining whether second metadata stored in the volatile memory and associated with the second logical address is corrupted, and performing an operation of accessing the non-volatile memory based on the second metadata, when the second metadata is not determined to be corrupted.
