then reads the 512 bytes of data from the buffer.

At command completion, the Command Block Registers contain the cylinder, head and sector number 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 cylinder, head, and sector number of the sector where the error occurred. The flawed data is

pending in the sector buffer.

Read Verify Sector(s)

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 CompactFlash Storage Card sets BSY.

When the requested sectors have been verified, the CompactFlash Storage Card clears BSY and generates an

interrupt. Upon command completion, the Command Block Registers contain the cylinder, head, and sector

number of the last sector verified.

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.
