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. Output parameters to the device Sector Count This is the number of continuous sectors to be verified. If zero is specified, 256 sectors will be verified. LAB Low 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) LBA High/Low 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) H 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) R This is the retry bit; this bit is ignored. Input parameters from the device Sector Count This is the number of requested sectors not transferred. This number will be zero, unless an unrecoverable error occurs. LBA Low 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) Travelstar 5K100 Hard Disk Drive Specification 144
