Abstract

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.
