Table 137 Read Verify Sector(s) Command (40h/41h)
The Read Verify Sector(s) verifies one or more sectors on the device. No data is transferred to the host.
The difference between Read Sector(s) command and Read Verify Sector(s) command is whether the data is
transferred to the host or not.
If an uncorrectable error occurs, the read verify will be terminated at the failing sector.
