IOCTL_STORAGE_PREDICT_FAILURE vs StorageDeviceManagementStatus

EatonEaton Member Posts: 8

IOCTL_STORAGE_PREDICT_FAILURE has been around for a while and is a simple way to check a device for imminent failure.
StorageDeviceManagementStatus, when used in IOCTL_STORAGE_QUERY_PROPERTY, is a newer API introduced in Windows 10. Documentation on it is very sparse and no one seems to use it.
My question is, do both of these check the same information? Does STORAGE_PREDICT_FAILURE->PredictFailure relate to STORAGE_DEVICE_MANAGEMENT_STATUS->Health?

I'm basically trying to figure out if there is any reason to use IOCTL_STORAGE_PREDICT_FAILURE over the newer StorageDeviceManagementStatus, which contains more information, but I'm not sure if it is the same information.

    Well, the difference appears to be that StorageDeviceManagementStatus is more reliable - IOCTL_STORAGE_PREDICT_FAILURE always seems to fail with an error (and not because the storage is failing).
