12.20.1 General Purpose Log Directory The figure below defines the 512 bytes that make up the General Purpose Log Directory. Table 108: General Purpose Log Directory Description General purpose logging version Number of sectors in the log at log address 01h (7:0) Number of sectors in the log at log address 01h (15:8) Number of sectors in the log at log address 01h (7:0) Number of sectors in the log at log address 01h (15:8) ... Number of sectors in the log at log address 20h (7:0) Number of sectors in the log at log address 20h (15:8) Number of sectors in the log at log address 21h (7:0) Number of sectors in the log at log address 21h (15:8) Number of sectors in the log at log address 22h (15:8) ... Number of sectors in the log at log address 80h (7:0) Number of sectors in the log at log address 80h (15:8) ... Number of sectors in the log at log address FFh (7:0) Number of sectors in the log at log address FFh (15:8) Bytes Offset 2 00h 1 02h 1 03h 1 04h 1 05h 1 40h 1 41h 1 42h 1 44h 1 45h 1 100h 1 101h 1 1FEh 1 1FFh 512 The value of the General Purpose Logging Version word shall be 0001h. A value of 0000h indicates that there is no General Purpose Log Directory. The logs at log addresses 80-9Fh shall each be defined as 16 sectors long. Deskstar 7K400 Hard Disk Drive Specification 152
