The STORAGE_PREDICT_FAILURE structure is used in conjunction with IOCTL_STORAGE_PREDICT_FAILURE to report whether a device is currently predicting a failure.
Indicates when nonzero that the device is currently predicting an imminent failure.
Contains an array that holds 512 bytes of vendor-specific information if the device supports failure prediction.
Upon receiving an IOCTL_STORAGE_PREDICT_FAILURE device control request, the disk class driver attempts to verify if an IDE drive supports SMART. If the drive is a SCSI drive, the class driver attempts to verify if the SCSI disk supports the equivalent IDE SMART technology: Information Exception Control Page, X3T10/94-190 Rev 4.
If the device does not support failure prediction, the disk class driver fails the IRP with a status of STATUS_INVALID_DEVICE_REQUEST.
If the device supports failure prediction, the disk class driver queries the device for failure prediction status. If the device has bad sectors and predicts a failure, the disk class driver returns a nonzero value in PredictFailure. If status indicates that the device does not predict any failures at this time, the disk class driver returns a value of 0 in PredictFailure.
