How to pick the right tool (quick)
- Need full repair and export to live SQL: choose EaseUS or Stellar.
- Want a free, fast viewer for occasional checks: SysTools or RecoveryTools.
- Concerned about severe corruption or forensic recovery: Stellar or paid SysTools Pro.
- Prefer not to install SQL Server and only inspect files: Aryson or dedicated MDF viewers.
- Want full SQL accuracy and querying: attach the MDF in SQL Server Express / SSMS.
Quick usage checklist
- Make a copy of the MDF (and matching NDF/LOG) before opening.
- Scan/preview in the viewer; use read‑only or “preview” mode when available.
- If exporting to SQL, stop SQL Server services if replacing files, or export via the tool to a new database.
- Verify exported data with queries in SSMS.
Security and reliability tips
- Download tools from vendor sites only; verify checksums and scan installers.
- Prefer tools with a preview/demo so you can confirm they read your data before purchase.
- For critical recovery, test on copies and consider vendor support or professional recovery services.
