Build Plan: PartitionGuard
● Live prototype This tool has a working CLI/web build you can try right now →Concept PartitionGuard — Disk Operations Suite cluster, Vertical variant.
Summary
Reads a disk image’s partition table and checks whether it contradicts itself.
Partition tools sell wizards but hide risk. Add preflight analysis, simulated plan, backup checkpoint, and rollback.
Primary persona
The Specialist — a user in pc repair shops and storage-heavy workstations, whose day-to-day workflow this variant is purpose-built around — not a generic power user.
Target customer (from research): PC repair shops and storage-heavy workstations.
Competitive inspiration
We’re combining the strongest parts of tools people already pay for:
| Source app | Modeled annual revenue | Current stack |
|---|---|---|
| EaseUS Partition Master Professional | $5.0M | C++ native disk core |
| AOMEI Partition Assistant Professional | $5.0M | C++ native disk core |
| DiskGenius Professional | $3.4M | C++ native |
| Hard Disk Sentinel Professional | $3.4M | Delphi/native Windows |
Combined addressable revenue pool (modeled): $16.8M. Target capture rate: 4.8%.
Feature scope
v1 (MVP — ship this, nothing more):
- Partitioning
- Cloning
- Migration
- Bad-sector awareness
- SMART
v2 (after v1 has real usage data):
- Disk map
- Safe operation planning
Architecture sketch
- Core engine: Rust storage engine
- Application shell: C#/.NET 10 WinUI 3; C
- Supporting component: /WDK only where needed
The split matters more than the exact tech: keep the engine (file I/O, hashing, scanning, capture — whatever is CPU/IO heavy) decoupled from the UI shell, so the engine can be tested headless and reused across variants in this cluster.
Roadmap
| Phase | Focus | What happens |
|---|---|---|
| Weeks 1–10 | Core engine spike | Stand up the riskiest part of the tech stack first (the engine, not the UI) against real sample data and confirm the approach holds up. |
| Weeks 11–33 | v1 feature build-out | Build the full v1 feature scope below on top of the proven engine, wiring up the UI shell as features land. |
| Weeks 34–44 | Polish, packaging & soft launch | Crash/usage instrumentation, code signing, pricing/licensing wiring, and a soft launch to a small user group. |
- MVP timeline: 28–44 weeks
- Build simplicity: 3/10 (higher = simpler)
- Opportunity score: 6.3/10
Go-to-market
- Partnerships and sponsorships inside the specific niche community
- Integrations / import-export support for the niche’s existing tools
- Targeted content marketing built around the specific workflow, not the category
- A referral program seeded through the niche community’s existing influencers
Success metrics
- Activation: % of installs that complete the core action (the thing in “Feature scope v1”) within the first session
- Retention: 30-day active rate among installs that activated
- Monetization: trial-to-paid conversion rate, tracking toward the $806K/yr mid revenue scenario within 12 months of launch
- Quality: crash-free session rate ≥ 99.5% before removing the “beta” label
Risks & mitigations
| Risk | Why it matters | Mitigation |
|---|---|---|
| Naming risk | The working name has a flagged trademark/domain collision and cannot be used as the shipping brand as-is. | Run a formal name-clearance pass (trademark + domain + store-listing search) before any public landing page, build, or store listing goes live. |
| Market risk | Users already pay for the incumbent tools this concept borrows from and may see little reason to switch. | Lead marketing with the specific market gap this product closes, not a feature checklist — differentiation is the pitch, not parity. |
| Distribution risk | New, unsigned Windows apps routinely get flagged by SmartScreen or Store review, which kills first-run trust. | Budget for a code-signing certificate and Microsoft Store review lead time before any public launch date is promised. |
| Technical risk | Deeper OS/hardware integration (drivers, SMART data, low-level file APIs) adds real platform risk beyond typical CRUD app work. | Spike the riskiest OS integration point in week 1, before committing to the rest of the UI — kill or de-scope early if it doesn’t check out. |
Revenue scenario (modeled, not a forecast)
| Scenario | Estimated annual revenue |
|---|---|
| Low | $363K |
| Mid | $806K |
| High | $1.5M |
Pricing
$49–$149/yr depending value
Naming status
Working name only — brand verdict CAUTION (Medium). Collision: PartitionGuard. Prefer a more distinctive software mark.
This is a working title for planning purposes. Clear the name (trademark + domain + marketplace search) before any public build, landing page, or store listing.
Build checklist
- Validate demand (forum/Reddit/community signal check for the disk operations suite job-to-be-done)
- Clear the working name (trademark, domain, store listing collisions)
- Spike the core engine described in the architecture sketch above
- Ship a thin end-to-end MVP covering the v1 feature scope only
- Instrument usage + crash reporting before wider release
- Set up licensing/payment (one-time key or subscription per pricing direction)
- Soft-launch to a small user group and gather pricing/feature feedback
- Revisit the v2 feature list using real usage data, not guesses
Notes
Working product name only; validate trademarks/domains and user demand before build.
