The READ VERIFY SECTORS EXT command is same as the READ SECTORS EXT command, except that

DRQ is never set and no data is transferred to the host. When the requested sectors have been verified, the

device clears BSY and generates an interrupt. Upon command completion, the Command Block Registers

contain the 48-bit LBA address 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 48-bit LBA address of the sector

where the error occurred. The Sector Count Register contains the number of sectors not yet verified.
