Disk Health Viewer (SMART)

Portable disk health / SMART viewer for Windows, built with AutoIt + smartctl + a small Python helper.
It shows a quick overview, health summary (warnings), and a SMART items table, and can export TXT/HTML reports or copy a clean report to clipboard.

---

Features

• List physical disks (WMI)
• Read SMART via smartctl (supports SATA/SAS/NVMe)
• Overview: model, serial, temp, power-on hours, protocol, SMART health
• Health summary: Overall (OK/WARNING/BAD/UNKNOWN) + warnings list
• SMART Items table with Severity column (auto-sorted)
• Export:
  • TXT (raw helper output)
  • HTML (client-friendly report)
• Copy Report button (clipboard)

Grab the latest compiled release from the GitHub Releases page.

If you build from source, see the “Build / Development” section below.

Requirements (for users)

• Windows 10/11
• Run as Administrator (recommended) for best SMART access
• The app is portable: no installer

Folder structure (portable)

Put the EXE next to the tools folder like this:

DiskHealthViewer\
  DiskHealthViewer.exe
  DiskHealthViewer.ico
  tools\
    smartctl.exe
    smartread.py        (or smartread.exe)
    python\python.exe   (optional portable python)

smartctl.exe is required.
The helper can be either:

• tools\smartread.exe (best: no Python required), OR
• tools\smartread.py (works with embedded python or system python)

---

How to use

1. Right-click the app → Run as administrator
2. Click Refresh to list disks
3. Click a disk to select it
4. Click Load SMART (or double-click the disk)
5. Use:
   • Copy Report → paste into notes/email/tickets
   • Export TXT → saves raw helper output
   • Export HTML → saves a nice report for clients

---

Troubleshooting

“No SMART data” / “UNKNOWN”

• Run as Administrator
• Make sure tools\smartctl.exe exists
• Some USB enclosures don’t expose SMART properly. Try:
  • a different USB enclosure
  • direct SATA/NVMe connection
  • different smartctl device options (advanced users)

The app can’t find Python

You have 3 options:

1. Recommended: build/use tools\smartread.exe
2. Include embedded python: tools\python\python.exe
3. Use system python installed in PATH

Antivirus false positives

Portable tools that bundle executables sometimes trigger false positives (especially with AutoIt-packed binaries).
Best practice:

• publish hashes (SHA-256) in Releases
• sign the EXE if you have a code signing cert
• keep sources public for transparency

Build / Development (from source)

Repo contents (typical)

DiskHealthViewer\
  DiskHealthViewer_v1.2.3.au3
  DiskHealthViewer.ico
  tools\
    smartctl.exe
    smartread.py

1) AutoIt (GUI app)

Requirements:

• AutoIt v3.3.16.1 (or compatible)
• SciTE / AutoIt3Wrapper (comes with AutoIt)

Steps:

1. Open DiskHealthViewer_v1.2.3.au3
2. Ensure the icon directive is set (optional but recommended):

   #AutoIt3Wrapper_Icon=DiskHealthViewer.ico

3. Compile (SciTE → Tools → Compile or press F7)

Output:

• DiskHealthViewer.exe

2) Python helper (smartread.py)

The GUI calls the helper like this:

• smartread.exe --device "<DeviceID>" --smartctl "<path to smartctl.exe>" or
• python smartread.py --device "<DeviceID>" --smartctl "<path to smartctl.exe>"

So the helper must output the expected sections:

• OVERVIEW
• SUMMARY
• ITEMS

3) Optional: build smartread.exe (recommended for portability)

Why: users won’t need Python installed.

Common approach:

• Use PyInstaller on a dev machine:

  pyinstaller --onefile smartread.py --name smartread
  

• Put the result as:
  • tools\smartread.exe

(Exact build flags may vary depending on your Python environment.)
