If an uncorrectable error occurs, the write will be terminated at the failing sector Output Parameters To The Device Feature Current The number of sectors to be transferred low order, bit (7:0) Feature Previous The number of sectors to be transferred high order, bit (15:8) T TAG value. It shall be assigned to be different from all other queued commands. The value shall not exceed the maximum queue depth specified by the Word 75 of the Identify Device information. LBA Low Current LBA (7:0). LBA Low Previous LBA (31:24). LBA Mid Current LBA (15:8). LBA Mid Previous LBA (39:32). LBA High Current LBA (23:16). LBA High Previous LBA (47:40). F FUA bit. When the FUA bit is set to 1, the completion status is indicated after the transferred data are written to the media also when Write Cache is enabled. When the FUA bit is set to 0, the completion status may be indicated before the transferred data are written to the media successfully when Write Cache is enabled.
