6.20 Read Sector(s) (20h)
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 36 defines the Read Sector command Byte sequence.

6.21 Read Sectors Ext (24h) 48bit LBA
This command reads from 1 to 65536 sectors as specified in the Sector Count Register. A sector count of 0
requests 65536 sectors. The transfer begins at the specified LBA. When this command is issued and after each
sector of data (except the last one) has been read by the host, the CompactFlash TM Storage Card 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.
At command completion, the Command Block Registers contain the LBA of the last sector read. If an error occurs,
the read terminates at the sector where the error occurred. The Command Block Registers contain the LBA of the
sector where the error occurred. The flawed data is pending in the sector buffer.

6.22 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.
