The Read Verify Sector(s) command verifies one or more sectors on the device. No data is transferred to the host.
The difference between the Read Sector(s) command and Read Verify Sector(s) command is that data is transferred
to the host during a Read Sectors command and data is not transferred to the host during a Read Verify Sectors
command.
If an uncorrectable error occurs, the read verify will be terminated at the failing sector.

This is the number of continuous sectors to be verified. If zero is specified, 256 sectors
will be verified.
This is the sector number of the first sector to be transferred. (L = 0)
In LBA mode this register contains the LBA bits 0–7. (L = 1)
This is the cylinder number of the first sector to be transferred. (L = 0)
In LBA mode this register contains the LBA bits 8–15 (Mid) and bits 16–23 (High).
(L = 1)
This is the head number of the first sector to be transferred. (L = 0)
In LBA mode this register contains the LBA bits 24–27. (L = 1)
This is the retry bit; this bit is ignored.
This is the number of requested sectors not transferred. This number will be zero, unless
an unrecoverable error occurs.
This is the sector number of the last transferred sector. (L = 0)
In LBA mode this register contains the current LBA bits 0–7. (L = 1)
