[. . . ] Error Register A read-only register containing specific information regarding the previous command. Data interpretation differs depending on whether the controller is in operational or diagnostic mode. A power up, reset, software reset, or receipt of a diagnostic command sets the controller into diagnostic mode. Issuing any command (apart from a Diagnostic command) places the controller into operational mode. In operational mode, the Error register is valid only when the Error bit in the Status register is set. The bit definitions for operational mode follow:
7 0 Interface CRC 6 ECC D at a ECC Error 5 0 Not U se d 4 ID N F ID Not Found 3 0 Not U se d 2 ABRT A b o rte d C o m m an d 1 TK0 Track 0 Error 0 AM NF Address Mark Not Found
Interface CRC An interface CRC error occurred during an Ultra DMA transfer. Data ECC Error An non-correctable ECC error occurred during a Read Sector command. Firmware Problem Indicates a firmware problem was detected, (e. g. , invalid interrupt, divide overflow). ID Not Found Either a matching ID field not found, or a CRC error occurred. Aborted Command Invalid commands, write fault, no seek complete, or drive not ready. Track 0 Error Track 0 was not found during execution of a Restore command. Address Mark Not Found The Address Mark could not be found after an ID match.
Features Register Enables or disables features through the Set Features command.

HOST SOFTWARE INTERFACE
Sector Count Register Holds the number of sectors to be sent during a Read or Write command, and the number of sectors per track during a Format command. If an error occurs during such an operation, this register contains the remaining number of sectors to be transferred. Sector Number Register Holds the starting sector number for any disk operation. The register is updated as each sector is processed in a multi-sector operation. Cylinder Number Registers Two 8-bit Cylinder Number registers (Low and High) specify the starting cylinder for disk operation. Device/Head Register Used to specify the drive and head number to be operated on during any disk operations. Within the context of a Set Parameters command, this register specifies the maximum number of heads on the drive. Bit definitions follow:
7 1 6 LBA M ode 5 1 4 DRV S e le c t Drive 3 HS3 S e le c t 2 HS2 H e ad S e le c t 1 HS1 H e ad S e le c t 0 HS0 H e ad S e le c t
Select LBA Mode Enabling this bit for commands not supported by LBA mode will abort the selected command. When set, the Task File register contents are defined as follows for the Read/Write and translate command:
CO N TEN TS S e c to r N u m b e r Cylinder Low Cylinder High Drive/Head L B A B IT S 0-7 8 - 15 16 - 23 24 - 27
Drive Select Set to 0 to select the master drive; set to 1 to select the slave drive. Head Select Specifies the binary coded address of the head to be selected.
Status Register Contains results of the last command executed, and the drive's status. The other seven Task File registers may be read only when bit 7 (BUSY) of the Status register is low. [. . . ] Save Attribute Value This feature saves the current attribute values to non-volatile storage. Perform Off-Line Data Collection Data is collected from random seeks, timed pattern seek times and head margin tests. Return Status This feature allows the host to assess the status of a S. M. A. R. T. capable device by comparing all saved attribute values with their corresponding warranty failure thresholds. [. . . ]
