Table 91 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 of Read Sector(s) command and Read Verify Sector(s) command is whether the data is
transferred to the host or not.
transferred to the host or not.
If an uncorrectable error occurs, the read verify will be terminated at the failing sector.
Output Parameters To The Device
Sector Count
Sector Count
The number of continuous sectors to be verified. If zero is specified, then 256
