Virtual-Storage-Fault-Lab

I develop Virtual Storage Fault Lab for Windows QA: fail every Nth matching read/write on its 64 MiB RAM disk. Physical drives aren't targets. MIT app/SDK; private driver, OEM terms by quote. titanfyre/Virtual-Storage-Fault-Lab AI-assisted.

Inject bounded read/write errors into a 64 MiB Windows lab disk (C++17) I maintain Virtual Storage Fault Lab for testing how Windows software handles storage I/O errors. A private Storport driver exposes one disposable 64 MiB RAM-backed disk; the native UI, CLI and two-file C++17 SDK control a fault policy on that disk. Choose a sector range, read/write direction and every Nth matching request to fail. For example, fail every fourth matching read. Windows can retry requests, so that isn't a promise that exactly every fourth application call fails. Changing a policy doesn't generate a workload or format a disk. Use disposable fixtures: injected errors can make a mounted lab filesystem unusable. The SDK accepts no physical-drive path. The validation notes document Windows 10 x64 VM installation/runtime/removal tests, including Driver Verifier. Windows 11, Secure Boot/HVCI and broader deployment qualification remain pending. Public application/SDK/installer source is MIT. The signed private driver has separate evaluation/commercial terms; this evaluation has no enforced trial timer or online activation. Production/OEM integration and support are separate offerings. The README has the exact tested scope and installation details.
