Microsoft crash telemetry found 'no chkdsk bug' in Windows 7 RTM

Steven reports about Windows 7 RTM chkdsk bug, “We first looked through our crash telemetry (both at the user level and “blue screen” level) and found no reported crashes of chkdsk. We of course look through our existing reports of issues that came up during the development of Windows 7, but we didn’t see anything at all there. We queried the call stacks of existing reported crashes (of all kinds, since this was reported) and we did not find any crashes with chkdsk.exe running while crashing. We then began automated test runs on a broad set of machines—these ran overnight and continued for 2 days. We also saw reports related to a specific hardware configuration, so we set up over 40 machines based on variants of that chipset, driver, and firmware and ran those tests. We were not hitting any crashes (as mentioned, the memory usage was already understood). Because some were saying the machines were non-responsive we also looked for that in manual tests and didn’t see anything. We also broadened this to request globally to Microsoft folks to try things out (we have quite a few unique configs when you think of all of our offices around the world) and so we had several hundred more test runs going. We also had reports of the crash happening when running without any virtual memory—that could be the case, but that would not be an issue with this utility as any program that requests more memory than physically available would cause things to tip over and this configuration is not recommended for general purpose use (and this appears to be the common thread on the small number of non-reproducible crashes).” Also refer this Mark’s post, and Steven's full post.
