SAVER_MTBFIOERROR
SAVER MTBF I/O error bucket for SAVER_MTBFIOERROR
SAVER_MTBFIOERROR is bug check code 0x0000F103.
This reliability-test bucket points at I/O failure during an MTBF path. It should be correlated with storage, filesystem, device, or network I/O logs depending on the stack recorded in the dump.
How to read it in a dump
- Treat this value as an internal diagnostic bucket from the Windows SAVER family, not as a classic blue-screen stop code with public parameter semantics.
- the useful evidence is the dump type, WER bucket, triggering process, provider-specific data, and event-log context around the capture.
- the symbolic name narrows the subsystem that requested capture; it does not by itself identify a defective driver or application.
What to check
- Check disk, storage controller, filesystem, and device events around the capture.
- Identify the I/O target and request type from the dump stack.
- Do not assume physical disk failure without matching error records.
