STATUS_PARITY_ERROR
A parity check failed during the I/O transfer
Parity is used by some buses, controllers, and memory or data paths to detect bit errors. This status means the transfer failed an integrity check before the higher-level format could accept the data. It does not identify whether the fault originated in media, cabling, controller logic, or host hardware.
Correlate the error with transport logs, hardware counters, and other devices on the same path. Retrying can distinguish a transient link event from a persistent fault, but repeated successful retries do not make silent corruption acceptable. Preserve the original command and any sense or controller data.
What to inspect
- Record controller, bus, target, command, offset, and low-level error data.
- Inspect cables, termination, link counters, controller firmware, and shared-path errors.
- Escalate recurring parity faults before trusting writes or recovered reads.
