Cylinder high : 07h = word 7 is invalid Cylinder low : 03h = bit 3 is invalid Sector count : 04h = now Security feature set is enabled Word Content 0 0001h Data Structure revision 1 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 2 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 3-6 Maximum LBA address 7 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 8-254 Reserved 255 Integrity word 15-8 Checksum 7-0 Signature (A5h) Figure 78. Device Configuration Overlay Data structure Note: Bits 7-0 of this word contain the value A5h. Bits 15-8 of this word contain the data structure checksum. The data structure checksum is 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 is added with unsigned arithmetic, and overflow is ignored. The sum of all bytes is zero when the checksum is correct. Hitachi Travelstar 60GH & 40GN hard disk drive specifications 114
