Sector Count register. A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in
the Sector Number register.
21. READ VERIFY SECTOR(S) (code: 40h or 41h): This command is identical to the READ SECTORS
command, except that DRQ is never set and no data is transferred to the host .
22. RECALIBRATE (code: 1Xh): This command return value is select address mode by the host request.

disable PIO 8 bit transfer mode between the host and the device.
26. SET FEATURES SET 4BYTES APPENDED ( code: EFh): This command allows the host to set the 4
byte data appended to the data transfer on Read Long and Write Long commands.
27. SET MAX ADDRESS (code: F9h): This command allows the host to redefine the maximum address of
the user-accessible address space.
28. SET MAX SET PASSWORD ( code: F9h): This command requests a transfer of a single sector of data
