IDENTIFY_DEVICE_DATA structure (ata.h)
The IDENTIFY_DEVICE_DATA structure contains the data retrieved by an ATA identify device data command (0xEC).
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.
