4. Unexplainable Field Phenomena Microsoft has been tracking these for years Things aren’t getting better Customers expect a solution from us We have nothing to give them There are 2 theories The device has a flaw The device has been mishandled Microsoft has been tracking these for years Things aren’t getting better Customers expect a solution from us We have nothing to give them There are 2 theories The device has a flaw The device has been mishandled 2010-04-20Microsoft Corporation4

5. Theory #1: The device has a flaw Goal: Address the flaw. Assumption: ATA devices are sophisticated enough to perform their own internal ‘crashdump’. Microsoft is not able to address these issues along. Digression: Microsoft attempt to do this with the millions of crash reports it receives every day In general, user mode crashes are available to partners from http://winqual.microsoft.com through different portals. http://winqual.microsoft.com Partners with kernel mode drivers can download ~50 randomly selected CABs for a given bucket through the WER portal Partners only receive external mini dumps. Full dumps and internal crashes may only be given out by selected groups. Kernel mode crashes typically are driver issues that cause Blue Screens of Death or reset the machine. Analysis of data has found that device failure is a significant source of perceived “driver issues”. Goal: Address the flaw.

11. Theory #2: The device has been mishandled Goal: Enable proper device handling. Assumptions: Device has background scan information about internal issues, error handling, and results attempted corrections. This background scan information would be useful to manufacturers if there was a method for delivering it from active deployed systems. Background scanning can result in actionable requests from devices, improving robustness, and raising handling issues to the users attention. Goal: Enable proper device handling.
