ERROR INFORMATION EXAMPLE 2: If the device has enabled the Security feature set and if a user attempts to disable that feature, the device aborts that command and returns an error reason code as below. Cylinder high Cylinder low Sector count : 07h : 03h : 04h = word 7 is invalid = bit 3 is invalid = now Security feature set is enabled Word 0 1 2 3-6 7 8-254 255 Content 0001h Data Structure revision Multiword DMA modes supported 15-3 Reserved 2 1 = Multiword DMA mode 2 and below are supported 1 1 = Multiword DMA mode 1 and below are supported 0 1 = Multiword DMA mode 0 is supported Ultra DMA modes supported 15-6 Reserved 5 1 = Ultra DMA mode 5 and below are supported 4 1 = Ultra DMA mode 4 and below are supported 3 1 = Ultra DMA mode 3 and below are supported 2 1 = Ultra DMA mode 2 and below are supported 1 1 = Ultra DMA mode 1 and below are supported 0 1 = Ultra DMA mode 0 is supported Maximum LBA address Command set/feature set supported 15-8 Reserved 7 1 = Host Protected Area feature set supported 6-4 Reserved 3 1 = Security feature set supported 2 1 = SMART error log supported 1 1 = SMART self-test supported 0 1 = SMART feature set supported Reserved Integrity word. See note below. 15-8 Checksum 7-0 Signature (A5h) Figure 78. Device Configuration Overlay Data structure Note: Bits 7:0 of this word shall contain the value A5h. Bits 15:8 of this word shall contain the data structure checksum. The data structure checksum shall be the two's complement of the sum of all byte in words 0 through 254 and the byte consisting of bits 7:0 of word 255. Each byte shall be added with unsigned arithmetic, and overflow shall be ignored. The sum of all bytes is zero when the checksum is correct.
