Command 48, Additional Device Status Bytes
Table 12 below summarizes the Command 48 Additional Device Status bytes. This is a 6-byte field. The remaining status bytes are
reserved for future use. A status bit is cleared (0) for no error. A status bit is set (1) when an error (or condition) is detected.
