The data is then written to the disk media. The sectors are transferred through the Data Register 16 bits at a time. If an uncorrectable error occurs, the write will be terminated at the failing sector, when the auto reassign function is disable. Output parameters to the device Sector Count This indicates the number of continuous sectors to be transferred. If the Sector Count of zero is specified, 256 sectors will be transferred. LBA Low This indicates 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/Mid This indicates 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 indicates 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 indicates the retry bit; this bit is ignored. Input parameters from the device Sector Count This indicates the number of requested sectors not transferred. The Sector Count will be zero unless an unrecoverable error occurs. LBA Low This indicates 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 198
