STORAGE_PROTOCOL_ATA_DATA_TYPE enumeration (winioctl.h)

The ATA protocol data type.

Syntax

typedef enum _STORAGE_PROTOCOL_ATA_DATA_TYPE {
  AtaDataTypeUnknown = 0,
  AtaDataTypeIdentify,
  AtaDataTypeLogPage
} STORAGE_PROTOCOL_ATA_DATA_TYPE, *PSTORAGE_PROTOCOL_ATA_DATA_TYPE;

Constants

AtaDataTypeUnknown Value: 0 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.
