Figure 91. Read Verify Sectors Command (40h/41h)
The Read Verify Sectors verifies one or more sectors on the device. No data is transferred to the host.
The difference of Read Sectors command and Read Verify Sectors 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.
The retry bit. If set to one, then retries are disabled.R
The head number of the first sector to be transferred. (L=0)
In LBA mode, this register contains LBA bits 24 - 27. (L=1)
H
The cylinder number of the first sector to be transferred. (L=0)
In LBA mode, this register contains LBA bits 8 - 15 (Low), 16 - 23 (High). (L=1)
Cylinder High/Low
The sector number of the first sector to be transferred. (L=0)
In LBA mode, this register contains LBA bits 0 - 7. (L=1)
Sector Number
The number of continuous sectors to be verified. If zero is specified, then 256
sectors will be verified.
