If an uncorrectable error occurs, the read will be terminated at the failing sector.
Output Parameters To The Device
Feature Current | The number of sectors to be transferred low order, bits (7:0) |
Feature Previous | The number of sectors to be transferred high orde r, bits (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 requested data is always retrieved from |
| the media regardless of whether the data are held in the sector buffer or not. When |
| the FUA bit is set to 0, the data may be retrieved from the media or from the cached |

P | Priority bit. When the Priority bit is set to 1, the device attempts to provide better |
| quality of service for the command than normal priority commands. |
