STORAGE_PROTOCOL_ATA_DATA_TYPE enumeration (ntddstor.h)

The ATA protocol data type.

Note

The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.

Syntax

typedef enum _STORAGE_PROTOCOL_ATA_DATA_TYPE {
  AtaDataTypeUnknown,
  AtaDataTypeIdentify,
  AtaDataTypeLogPage
} STORAGE_PROTOCOL_ATA_DATA_TYPE, *PSTORAGE_PROTOCOL_ATA_DATA_TYPE;

Constants

AtaDataTypeUnknown Unknown data type.
AtaDataTypeIdentify Identify device data type.
AtaDataTypeLogPage Log page data type.

Remarks

When using IOCTL_STORAGE_QUERY_PROPERTY to retrieve protocol-specific information in the STORAGE_PROTOCOL_DATA_DESCRIPTOR, configure the STORAGE_PROPERTY_QUERY structure as follows:

• Allocate a buffer that can contains both a STORAGE_PROPERTY_QUERY and a STORAGE_PROTOCOL_SPECIFIC_DATA structure.

• Set the PropertyID field to StorageAdapterProtocolSpecificProperty or StorageDeviceProtocolSpecificProperty for a controller or device/namespace request, respectively.

• Set the QueryType field to PropertyStandardQuery.

• Fill the STORAGE_PROTOCOL_SPECIFIC_DATA structure with the desired values. The start of the STORAGE_PROTOCOL_SPECIFIC_DATA is the AdditionalParameters field of STORAGE_PROPERTY_QUERY.

To specify a type of ATA protocol-specific information, configure the STORAGE_PROTOCOL_SPECIFIC_DATA structure as follows:

• Set the ProtocolType field to ProtocolTypeAta.

• Set the DataType field to an enumeration value defined by STORAGE_PROTOCOL_ATA_DATA_TYPE:

  • Use AtaDataTypeIdentify to identify the ATA drive.
  • Use AtaDataTypeLogPage to get log pages from the ATA drive.
