[. . . ] 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. 6­1 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. A value of zero in this register implies a transfer of 256 sectors. A multisector operation decrements the Sector Count register. 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. Reading any of the Task File registers when BUSY is high returns the value of the Status register. Reading the Status register also clears any interrupt request to the host. Bit definitions follow: 7 BUSY Controller Busy 6 DRDY Device Ready 5 DF Device Fault 4 DSC Device Seek Complete 3 DRQ Data Request 2 0 1 0 0 ERR Error Controller Busy ­ Goes active when a command is written to the Command register, indicating controller task execution. [. . . ] If any warranty failure threshold is exceeded, the drive is declared to have a negative health status. Executing this sub-command results in all attribute values being saved to non-volatile storage on the device. Enable/Disable Automatic Off-Line To enable this feature, set the Sector Count register to F1h or 0 to disable.
