If the command is terminated due to an error, the remaining number of
sectors of which data was not transferred is set in this register.
(4) READ VERIFY SECTOR(S) (X’40’ or X’41’)
This command operates similarly to the READ SECTOR(S) command except that
the data is not transferred to the host system.
After all requested sectors are verified, the device clears the BSY bit of the Status
register and generates an interrupt. Upon the completion of the command
execution, the command block registers contain the cylinder, head, and sector
number of the last sector verified.
If an unrecoverable error occurs, the verify operation is terminated at the sector
where the error occurred. The command block registers contain the cylinder, the
head, and the sector addresses (in the CHS mode) or the logical block address (in
the LBA mode) of the sector where the error occurred. The Sector Count register
indicates the number of sectors that have not been verified.
If a correctable error is found, the device sets the CORR bit of the Status register
to 1 after the command is completed (before the device generates an interrupt).
