  • Page 45: Read Buffer [E4H]

    6.3.2.3.2 Read Buffer [E4h] The Read Buffer command enables the host to read the current contents of the device's sector buffer. When this command is issued, the device sets BSY, sets up the sector buffer for a read operation, sets DRQ, clears BSY, and generates an interrupt. The host then reads up to 512 bytes of data from the sector buffer.

  • Page 46: Pio Data Out Commands

    6.3.2.4 PIO Data Out Commands Execution includes the transfer of one or more 512-byte sectors of data from the host to the device. 1) The host writes any required parameters to the Features, Sector Count, Sector Number, Cylinder Low, Cylinder High, and Device/Head Registers. 2) The host writes the command code to the Command Register.

  • Page 47: Format Track [50H]

    Multiple Mode command, which must be executed prior to the Write Multiple command, sets the block count of sectors to be transferred. When the Write Multiple command is issued, the Sector count Register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sector is not evenly divisible by the block count, as many full blocks as possible are transferred, followed by a final, partial block transfer.

  • Page 48: Read Verify [40H, 41H]

    6.3.2.5.2 Read Verify [40h, 41h] This command is same as the Read Sectors command, except that DRQ is never set and no data is transferred to the host. When the requested sectors have been verified, the device clears BSY and generates an interrupt.

  • Page 56: Smart Feature

    6.3.2.8 SMART Feature The intent of self-monitoring, analysis, and reporting technology (SMART) is to protect user data and minimize the likelihood of unscheduled system downtime that may be caused by predictable degradation and/or fault of the device. By monitoring and storing critical performance and calibration parameters, SMART devices attempt to predict the likelihood of near-term degradation or fault condition.

  • Page 57: Smart Device Error Log Reporting

    6.3.2.8.2 SMART Device Error Log Reporting The intent of SMART Device Error Log Reporting feature is to augment the SMART feature set to provide additional diagnostic information on device that have generated error conditions. The device retains a specified amount of previously executed commands, and write this data along with the time of a triggered error condition to the existing SMART Read Logging Sectors.

  • Page 58: Smart Disable Operations [B0H, Sub D9H]

    The SMART Enable Operations command enables access to all SMART capabilities within the device. Prior to receipt of this command attribute values are neither monitored nor saved by the device. The device will preserve the state of SMART (either enabled or disabled) across power cycles. Once enabled, the receipt of subsequent SMART Enable Operations commands shall not affect any of the attribute values.

    6.3.2.10 Protected Area Feature, Address Offset Feature 6.3.2.10.1 Protected Area Feature and Set Max Security Extension A reserved area for data storage outside the normal operating system is required for several specialized applications. Systems may wish to store configuration data or save memory to disk data in a location that operation system can not change.

  • Page 80: Address Offset Feature

    The Set Max Unlock command changes the device from the Set Max Locked mode to the Set Max Unlocked mode. The Set Max Freeze Lock command allows the host to disable the Set Max commands (including Set Max Unlock) until the next power cycle. When this command is accepted the device is in the Set Max Frozen mode.

    6.3.2.11 Device Configuration Overlay Feature The Device Configuration Overlay feature set allows a utility program to modify some of the commands, modes, and features sets that a device reports as supported in the IDENTIFY DEVICE command response as well as the capacity reported. Commands unique to the Device Configuration Overlay feature set use a single command code and are differentiated from one another by the value placed in the Features register.

  • Page 95: Note For Write Cache And Auto Reallocation

    6.3.2.12 Note For Write Cache and Auto Reallocation (1) Loss of data in write cache Write cache is a performance enhancement whereby the device reports as completion the write commands to the host as soon as the device has received all of the data into its cache buffer memory. This means that there is a possibility that power off even after write command completion might cause the loss of the data that the device has not written onto the media.
