Abstract
A method and apparatus for logging errors in a storage device. As commands are executed by the storage device a list of previously executed commands is maintained. When an error is detected by the storage device, the previously executed commands and certain error condition codes are stored in an error log in a non-volatile memory of the storage device. The storage device is responsive to a command for reading back the values contained in the error log for diagnostic purposes.
