Disk Health Monitor

Disk health utility for SMART checks, drive status review, and trend history.

Features

• Detects local block devices
• SMART health checks for SATA/SAS drives
• NVMe SMART log checks for NVMe drives
• Temperature and health trend snapshots
• Launch detailed SMART command output in terminal
• Linux: GTK4 UI
• Windows: PySide6 UI

Dependencies

Runtime

• Python 3.11+

Linux stack:

• GTK4 + PyGObject
• smartmontools (smartctl)
• nvme-cli (nvme) for NVMe details
• A supported terminal emulator (x-terminal-emulator, gnome-terminal, konsole, xfce4-terminal, kitty, alacritty, or xterm)
• Optional: pkexec for privileged reads without starting the app as root

Windows stack:

• PySide6 (Qt)
• Recommended: smartctl in PATH for SMART health/temperature data
• Optional: psutil for richer disk enumeration

Install smartctl on Windows:

winget install smartmontools.smartmontools

Then run Disk Health Monitor from an elevated terminal (Run as Administrator) for best SMART access.

The Windows app can also prompt to relaunch itself as Administrator when SMART access is blocked.

Build AppImage

Build requirements

python3 -m pip install --user pyinstaller

Install appimagetool in PATH, or place one of these files in ./tools/:

• appimagetool.AppImage
• appimagetool-x86_64.AppImage
