Does Block Noise change file size?

No. We overwrite in place so file size remains constant while the content becomes unusable.

Can I zero multiple segments?

Yes. Higher intensities blank several regions. Use the corruption report to see each offset.

When should I choose noise over zeros?

Random noise emulates hostile tampering, while zeros mimic hardware or transfer failures. Pick the one that matches your scenario.

Segment Destruction

Erase chunks to mimic partial data loss

Block Noise removes or replaces stretches of bytes so you can test how gracefully systems react to missing data.

Archive restore testing • Spreadsheet truncation drills • Video or audio drop-out simulations

How Block Noise works

Real-world outages often stem from truncated uploads or overwritten disk regions. Block Noise reproduces that scenario without shell scripts, letting you vary chunk sizes and placements for realistic rehearsals.

Contiguous segment targeting

Rather than sprinkling random flips, Block Noise wipes continuous regions to mimic disk corruption or network loss.

Entropy options

Choose between zeroing data (classic truncation) or filling with random noise to mimic malicious tampering.

Chunk telemetry

Corruption reports call out exactly which offsets were blanked so engineers can cross-reference logs.

Workflow recipe

1.
Choose representative sample
Use staging data that mirrors production scale.
2.
Dial chunk coverage
Increase intensity to wipe larger regions. Combine with deterministic seeds for reproducible placement.
3.
Run acceptance checks
Ensure your systems halt or provide meaningful remediation guidance when data disappears mid-stream.

Test plan checklist

Monitor logs for partial read warnings
Capture user-facing error messages
Document whether retries attempt recovery
