A method and system for detecting and reporting storage hardware failure prediction is disclosed. The method and system provide a standardized mechanism for any type of storage device to predict and report storage failures. This includes SMART SCSI devices, SMART ATA/ATAPI devices, non-SMART SCSI devices, non-SMART ATA/ATAPI devices, proprietary storage devices, and others such as CD-ROM drives, DVD ROMs, tape drives, and RAM disks. A device driver obtains failure prediction status information and propagates it to a management application. The information may be propagated via a failure prediction filter driver used to perform statistical analysis or proprietary access to the hardware. In a Windows operating environment, information is propagated from the device driver through a Windows Management Instrumentation component. The Windows Management Instrumentation component bridges the gap across user mode and kernel mode, thereby allowing management applications in user mode to obtain information from device drivers residing in kernel mode. A standardized set of APIs is provided for performing storage device failure prediction.
