This command performs the internal diagnostic tests
implemented by the drive. See ERROR register for dianostic
codes.
selected drive with a vender unique data pattern (typically
00h or FFh). This drive accepts a sector buffer of data from
the host to follow the command with the same protocol as
the Write Sector Command although the information in the
buffer is not used.
