This command writes the desired head and cylinder of the selected drive with a vendor unique data

pattern (typically FFH or 00H). To remain host backward compatible, the ADC expects a sector buffer of

data from the host to follow the command with the same protocol as the Write Sector(s) command

although the information in the buffer is not used by the ADC. If LBA=1 then the number of sectors to

format is taken from the Sec Cnt register (0=256). The use of this command is not recommended.

The Identify Drive command enables the host to receive parameter information from the ADC. This

command has the same protocol as the Read Sector(s) command. The parameter words in the buffer

have the arrangement and meanings defined in Table 3-4. All reserved bits or words are zero. Table 3-4

gives the definition for each field in the Identify Drive Information.
