5K250 SATA OEM Specification Data buffer test The data buffer is tested at power on reset and when a drive self-test is requested by the host. The test consists of a write/read '00'x and 'ff'x pattern on all buffers. Error recovery Errors occurring on the drive are handled by the error recovery procedure.

Page 29: Preventive Maintenance
In systems that use the Travelstar 5K250 consideration should be given to the design of the system power switch. Hitachi recommends that the switch operate under control of the host system, as opposed to being hardwired. The same recommendation is made for cover-close switches. When a hardwired switch is turned off, emergency unload occurs, as well as the problems cited in section 5.1, "Data loss by power...
Page 30 Simple power cycling of the drive invokes the emergency unload mechanism and subjects the HDD to nontypical mechanical stress. Power cycling testing may be required to test the boot-up function of the system. In this case HItachi recommends that the power-off portion of the cycle contain the sequence specified in section 6.3.6.2, "Required Power-Off Sequence”.

The interface conforms to the Working Document of Information Technology, AT Attachment 8 – ATA/ATAPI Command Set (ATA/ATAPI8-ACS) Revision 3f dated 11 Dec. 2006, with deviation as follows: S.M.A.R.T.
Page 44: Register Naming Convention
5K250 (SATA) OEM Specification 11.1 Register naming convention This specification uses the same naming conventions for the Command Block Registers as the ATA8-ACS standard. However, the register naming convention is different from that uses in the Serial ATA 2.6 specification. The following table defines the corresponding of the register names used in this specification with those used in the Serial ATA 2.6 specification.

5K250 (SATA) OEM Specification The host must set RST=1 and wait for at least 5 microseconds before setting RST=0, to ensure that the device recognizes the reset. -IEN Interrupt Enable. When IEN=0, and the device is selected, device interrupts to the host will be enabled.
Page 46: Lba Low Register
5K250 (SATA) OEM Specification When 48-bit addressing commands are used, the “most recently written” content contains LBA Bits 16-23, and the “previous content” contains Bits 40-47. The 48-bit Address feature set is described in “12.14 48-bit Address Feature Set”. 11.8 LBA Low Register This register contains Bits 0-7.
Page 47 5K250 (SATA) OEM Specification settled over a track. DSC is set to 0 by the device just before a seek begins. When an error occurs, this bit is not changed until the Status Register is read by the host, at which time the bit again indicates the current seek complete status.
Page 48: General Operation Descriptions
5K250 (SATA) OEM Specification 12 General Operation Descriptions 12.1 Reset Response There are three types of reset in ATA as follows: Power On Reset (POR) The device executes a series of electrical circuitry diagnostics, spins up the HDA, tests speed and other mechanical parametric, and sets default values. COMRESET COMRESET is issued in Serial ATA bus.

Page 51: Sector Addressing Mode
5K250 (SATA) OEM Specification 12.4 Sector Addressing Mode All addressing of data sectors recorded on the device’s media is by a logical sector address. The logical CHS address for HTS5425XXK9SA00 / HTS5425XXK9A300 is different from the actual physical CHS location of the data sector on the disk media. HTS5425XXK9SA00 / HTS5425XXK9A300 support both Logical CHS Addressing Mode and LBA Addressing Mode as the sector addressing mode.
Page 52: Table 34 Power Conditions
5K250 (SATA) OEM Specification Power Mode 12.5.1 The lowest power consumption when the device is powered on occurs in Sleep Mode. Sleep Mode When in sleep mode, the device requires a reset to be activated. Standby Mode The device interface is capable of accepting commands, but as the media may not immediately accessible, there is a delay while waiting for the spindle to reach operating speed.

5K250 (SATA) OEM Specification Transition Time 12.6.4 The transition time is dynamically managed by users recent access pattern, instead of fixed times. The ABLE-3 algorithm monitors the interval between commands instead of the command frequency of ABLE-2. The algorithm supposes that next command will come with the same command interval distribution as the previous access pattern.

5K250 (SATA) OEM Specification the device are predicting a lower probability of a degrading or fault condition existing. Accordingly, lower attribute values indicate that the analysis algorithms being used by the device are predicting a higher probability of a degrading or fault condition existing. There is no implied linear reliability relationship corresponding to the numerical relationship between different attribute values for any particular attribute.

5K250 (SATA) OEM Specification 12.11 Seek Overlap HTS5425XXK9SA00 / HTS5425XXK9A300 provide accurate seek time measurement method. The seek command is usually used to measure the device seek time by accumulating execution time for a number of seek commands. With typical implementation of the seek command, this measurement must including the device and host command overhead.

5K250 (SATA) OEM Specification The spare tracks for reassignment are located at regular intervals from Cylinder 0. As a result of reassignment, the physical location of logically sequenced sectors will be dispersed. Auto Reassign Function 12.13.1 The sectors that show some errors may be reallocated automatically when specific conditions are met. The spare tracks for reallocation are located at regular intervals from Cylinder 0.

5K250 (SATA) OEM Specification 12.15 Software Setting Preservation Feature Set When a device is enumerated, software will configure the device using Set Features and other commands. These software settings are often preserved across software reset but not necessarily across hardware reset. In Parallel ATA, only commanded hardware resets can occur, thus legacy software only reprograms settings that are cleared for the particular type of reset it has issued.
