Table 90 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.

If an uncorrectable error occurs, the read verify will be terminated at the failing sector.

Output Parameters To The Device

Sector Count

The number of continuous sectors to be verified. If zero is specified, then 256 sectors

 

will be verified.

LBA 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)

LBA High/Mid

The cylinder number of the first sector to be transferred. (L=0)

 

In LBA mode, this register contains LBA bits 8 - 15 (Mid), 16 - 23 (High). (L=1)

H

The head number of the first sector to be transferred. (L=0)

 

In LBA mode, this register contains LBA bits 24 - 27. (L=1)

R

The retry bit, but this bit is ignored.

Input Parameters From The Device

Sector Count

The number of requested sectors not verified. This will be zero, unless an unrecoverable

 

error occurs.

LBA Low

The sector number of the last transferred sector. (L=0)

 

In LBA mode, this register contains current LBA bits 0 - 7. (L=1)

LBA High/Mid

The cylinder number of the last transferred sector. (L=0)

 

In LBA mode, this register contains current LBA bits 8 - 15 (Mid), 16 - 23 (High).

 

(L=1)

H

The head number of the last transferred sector. (L=0)

 

In LBA mode, this register contains current LBA bits 24 - 27. (L=1)
