Table 51: Read native max address
The LBA bit shall be set to one to specify the address is an LBA. DEV shall specify the selected device.
The native drive size is given in Drive/Head, Cyl Hi, Cyl Low and Sector num register as LBA value.
8.16 Read Sector(s) (20h or 21h)
This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0
requests 256 sectors. The transfer begins at the sector specified in the Sector Number Register. When this
command is issued and after each sector of data (except the last one) has been read by the host, the Drive
sets BSY, puts the sector of data in the buffer, sets DRQ, clears BSY, and generates an interrupt. The host
then reads the 512 Bytes of data from the buffer.
If an error occurs, the read terminates at the sector where the error occurred. The Command Block Registers
contain the cylinder, head, and sector number of the sector where the error occurred. The flawed data are
pending in the sector buffer. Table 52 defines the Read Sector command Byte sequence.
Table 52: Read sector(s)
8.17 Read Verify Sector(s) (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. When the command is accepted, the Drive sets BSY. When the requested sectors
have been verified, the Drive clears BSY and generates an interrupt.
If an error occurs, the verify terminates at the sector where the error occurs. The Command Block Registers
contain the cylinder, head and sector number of the sector where the error occurred. The Sector Count
Register contains the number of sectors not yet verified.
Table 53 defines the Read Verify Sector command Byte sequence.

8.18 Recalibrate (1Xh)
This command is effectively a NOP command to the Drive and is provided for compatibility purposes. Table
54 defines the Recalibrate command Byte sequence.
