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.
Sector Number
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)
Cylinder High/Low
This indicates the cylinder number of the last transferred sector. (L = 0)
In LBA mode this register contains the current LBA bits 8–15 (Low) and bits
16–23 (High). (L = 1)
H
This indicates the head number of the last transferred sector. (L = 0)
In LBA mode this register contains the current LBA bits 24–27. (L = 1)
13.41 Write Verify (3Ch: vendor specific)
In the implementation of the drive the Write Verify command is exactly the same as the Write Sectors
command (30h). No read verification is performed after the write operation.
Refer to Figure 135, "Write Sectors Command (30h/31h)" on page 195 for parameters.
