Data Sheet
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.

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 ATA Flash Disk Controller sets BSY.
When the requested sectors have been verified, the ATA Flash Disk Controller 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.
