Disk Heal: Quick Guide to Repairing Corrupted Drives

Step-by-Step Disk Heal Tutorial for Windows and macOS

Overview

A concise, practical walkthrough to install and use Disk Heal to scan, repair common disk issues, and attempt file recovery on Windows and macOS.

Before you start

• Backup: Copy important files to an external drive or cloud before repairs.
• Power: Ensure laptop is plugged in; don’t interrupt power during operations.
• Permissions: You’ll need administrator (Windows) or administrator/root (macOS) privileges.

Windows

1. Download & install

1. Visit the official Disk Heal website and download the Windows installer.
2. Right‑click the installer → Run as administrator.
3. Follow prompts and accept permissions.

2. Launch and grant permissions

• Right‑click Disk Heal → Run as administrator.
• Allow any UAC prompts.

3. Initial scan

1. Select the target drive (e.g., C:, external USB).
2. Click Scan to run a quick surface/health check.
3. Wait for scan to complete; note errors listed (bad sectors, file system inconsistencies).

4. Repair file system errors

1. From the scan results, choose Repair file system or Fix errors.
2. Let Disk Heal run chkdsk-like repairs; this may require a reboot for system drives.
3. Reboot if prompted and allow automatic fixes.

5. Repair bad sectors

1. Select Surface test / Repair bad sectors.
2. Start low-level checks; this can be slow—monitor progress and avoid interrupting.
3. If sectors are remapped successfully, mark drive as degraded and plan replacement.

6. Recover lost files

1. Choose Recover files or Undelete.
2. Pick file types or folders to target, and set a destination on a different drive.
3. Start recovery; review recovered files and save important ones elsewhere.

7. Final verification

• Rerun a full scan to confirm repairs.
• Check SMART attributes (if available) for long‑term health indicators.

macOS

1. Download & install

1. Download the macOS Disk Heal app (or DMG) from the official site.
2. Open DMG → drag app to Applications.
3. If Gatekeeper blocks it, open System Settings → Privacy & Security and allow the app.

2. Grant permissions

• Open Disk Heal; when prompted, grant Full Disk Access and any required permissions in System Settings → Privacy & Security.
• Authenticate as an admin.

3. Initial scan

1. Select the drive (Macintosh HD or external).
2. Click Scan to check APFS/HFS+ structures and surface issues.
3. Review reported issues (catalog errors, corrupted metadata, bad blocks).

4. Repair file system with Disk Heal

1. Choose Repair file system; if it cannot repair the startup volume while macOS is running, Disk Heal will instruct you to boot to Recovery or use an external installer.
2. For startup drives, reboot into Recovery (Command‑R) and run Disk Heal from an external boot volume or use Disk Utility if Disk Heal provides instructions.

5. Repair bad blocks

• Run Surface/Block test; allow the app to remap or isolate bad blocks. Back up if remapping is extensive.

6. Recover deleted files

1. Choose File Recovery.
2. Select file types and destination (use an external drive).
3. Scan and restore recovered files to the external destination.

7. Post‑repair checks

• Re-scan to confirm issues resolved.
• Use Disk Utility’s First Aid and check S.M.A.R.T. status (for external drives using third‑party tools).

Troubleshooting & tips

• If Disk Heal fails to repair system boot errors, use OS-native tools: Windows Recovery Environment + chkdsk /f, macOS Recovery + Disk Utility First Aid.
• For physical drive failure (clicking noise, rapidly increasing bad sectors), stop using the drive and consider professional recovery.
• Keep OS and Disk Heal updated; run regular scans monthly.

Quick checklist (both OS)

• Backup important data first.
• Run initial scan.
• Repair file system.
• Repair bad sectors (if any).
• Recover files to a different drive.
• Re-scan and monitor SMART.
