A recording device has medium interface means ( 14 ) for interfacing with a storage medium ( 11 ) for recording data on the medium and retrieving data from the medium, and a host interface ( 15 ) for communicating with a host ( 13 ) via messages according to a protocol (ATA/ATAPI). The messages include a write command for writing data, and a read command for reading data. In existing protocols (MMC-3) unwritten areas are considered to be areas that are not yet formatted, and zero data is to be returned on a read command. The device has an error reporting unit ( 16 ) for reporting an error via an error message in the event that during reading an area is detected which is unwritten.
